Want to change a partition from xfs to ext3 but can't tell what to put for
stride.
man page says:
"stride=stripe-size
Configure the filesystem for a RAID array with
stripe-size filesystem blocks per stripe."
So, what is stripe size anyway? The same as chunk size?
Is the example in the raid howto section 5.11 still valid? (It still tells
about -R instead of -E. Seems a bit old.)
So going with -b 4096 for the ext3 with a 32k chunk size still comes down to a
stride of 8, correct?

my understanding (hey, I even had a quick look at the source) is that
you want blocksize * stripe-size = raid-stripe-size, where the latter
is chunksize * num-data-elements.
> So, what is stripe size anyway? The same as chunk size?
I don't know whether there's any agreed-on terminology. mke2fs wants to know
how many fs-blocks it'll take to span a whole set of raid chunks. that is,
a write of X will hit all the disks in parallel. writes that are full-stripe
(and aligned) don't require the read-mod-write cycle.

no, I don't think so - I think it should be chunksize*ndatadisks/fsblocksize...

This might not be strictly on-topic here, but you may provide
enlightenment, as a lot of web searching hasn't helpmed me so-far )-:
A client has bought some Dell hardware - Dell 1950 1U server, 2 on-board
SATA drives connected to a Fusion MPT SAS controller. This works just
fine. The on-board drives are mirrored using s/w RAID, which is great and
just how I want it.
The server also has 2 x Dell PERC dual-port SAS Raid Cards which have LSI
MegaRaid chipssets on them. One cable from each raid card connect to half
of a Dell external disk array box - 15 500GB SATA drives with a SAS
backplane, one card has 8 drives, the other 7. I want to run the RAID
cards in JBOD mode, so I can use linux s/w RAID. A nice little package,
which takes up 4U of rack space in total. (although the disk box is f'ing
heavy!!!)
And this is where I'm a little frustrated! I've compiled up a custom
kernel, (which is what I always do for my servers - no modules, no initrd,
this is 2.6.18), and at boot time the dmesg output sees the drives in the
external enclosure, but does not associate them to sdX drives! The
underlying distro is Debian stable, but I doubt theres anything of issue
there.
ie.:

etc. and it's repeated for the 2nd card. I've never seen this behaviour
before - normally it sees the drives, then associated them to sdX devices
- which is exactly what it does for the internal 2 drives:
On the internal drives, it goes like:

So it's a bit frustrating.
LUN support is enabled, and the boot-line is:
auto BOOT_IMAGE=Linux ro root=901 max_luns=8
So if it's a LUN issue, then they ought to be being probed...
I'm wondering about things like the controllers needing some poking at the
BIOS level, but I've looked and there isn't a JBOD mode - only various
built-in RAID modes, so I've not created any RAID sets through the BIOS (I
want raid 6 on this box over all 15 drives)
I'm sure it's something dead obvious, so any clues would be appreciated!
Thanks,
Gordon

Some RAID cards don't explicitly have a JBOD mode but instead an option
that says something like "Export unconfigured disks", and ISTR that
MegaRAID may be that sort of card. Poke about in the card BIOS a bit
more.

I have several Dell 2950s (same chassis) and they have this problem.
You can't do the PERC card and get JBOD basically. The PERC5 card has no
JBOD mode, whereas the PERC4 card did.
Dell said they may get a BIOS update, but wouldn't commit.
In the meantime, you have to exchange the PERC5 card for a SAS5 card,
then you can have JBOD.
I was a little disappointed, as the PERC5 card can drive 6 or 8 devices,
but the SAS5 card can only drive 4. Lame.

Ju,
Any word on this problem yet? Anything further that I can do to assist?
FYI: I'm going to be ordering a new server next week. Its hardware will be a close match to the troublesome system that I have in production. Hopefully, once it arrives I'll be able to do some serious testing on it and will be able to "hack" on it more severely than we could the production machine.
In the meantime, anything you can think of, or want me to try, to help the production machine I'd love to hear about it.

This server is an RSYNC hub for my company's three offices. Every night an on-site backup cache in each office pushes the day's data to this machine. After that process is complete, this machine creates a tarball of the combined sum of the three office's data to keep for short term storage. The machine also rotates these tarballs for a week, so I end up with 7 90+ GB tarballs.
The uncompressed data contains everything from Word documents to AutoCAD drawings to a backup of my e-mail data store and Jpeg pictures from a company party. You name it, I probably have it. ;-) The uncompressed data is floating around 140GB.
To create my tarball I simply run "tar -zcvf /daily/backup1/archive.tar.gz ." from inside of a perl script of my own creation. Nothing special about it.

If it is happening during disk I/O, I would like to investigate further.
It would be greatly helpful if you could provide some detail steps to get the issue including how to create that big size file.
And also, I'll check with F/W team to see if any updated version of it and will get back to you if so.
Thank you, again.

Firmware on the controller (from /proc/scci/scsi): 351S
=================================================================
Host: scsi2 Channel: 00 Id: 06 Lun: 00
Vendor: DELL Model: PV22XS Rev: E.18
Type: Processor ANSI SCSI revision: 03
Host: scsi2 Channel: 01 Id: 00 Lun: 00
Vendor: MegaRAID Model: LD 0 RAID5 858G Rev: 351S
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi2 Channel: 01 Id: 01 Lun: 00
Vendor: MegaRAID Model: LD 1 RAID5 858G Rev: 351S
Type: Direct-Access ANSI SCSI revision: 02
=================================================================
I have seen reports on Dells mailing list that elude to the fact the the E18 and 351S firmwares are supposed to help this situation, but not in my case. My system shipped with these firmwares in place. Dell, to my knowledge, does not offer any newer versions of either firmware.

As for other tasks, the machine also serves as a web server (Apache, MySQL and PHP) and e-mail relay (Postfix). The mail relay does more work than the web server, but even that is light.
Besides the external storage (powered by megaraid, the PERC4 and the PV220s) the machine has two internal SATA drives. These internal drives house the OS, the web server and the mail queue. The only I/O running through megaraid at the time of the failures has been the creation of the tar files.

It seems like that, for some reason, controller couldn't return commands (2 commands for this case) within given timeout period.
And because of it, driver decided to reset the controller and as part of reset, it triggers the F/W to make the device offline.
> b). Can lead me to a fix.
Can you clarify what is F/W version on the controller?
Besides disk I/O, are there other operations involved like, tape R/W?
How about application? Any application that is communicating with MegaRAID through IOCTL at that time?
Thank you,

Hi list,
I have a Dell PowerEdge 850 with their PERC4sc RAID card driving a Dell PowerVault 220s external drive enclosure running Ubuntu 5.10. This machine and all the parts that make it up are less than 2 months old. In that time, I have had both logical drives supplied by PV220s taken offline by the megaraid driver twice. The only cure for this has been a reboot of the machine. Luckily, with the exception of the process that was running at the time of the problem, nothing else was damaged or hurt; no loss of data has been experienced (yet).
Both times the failure has occurred, it happened while creating a gzipped tarball of some backup data. The final tarball created is averaging about 92+ GB in size and the machine is under heavy disk I/O for more than 7 hours. I have been able to grab this information from the syslog after the failure (gathered with LogWatch):
1 Time(s): [5535381.561000] megaraid abort: 55592075:43[255:128], fw owner
1 Time(s): [5535381.561000] megaraid abort: 55592077:62[255:128], fw owner

2 Time(s): [5535562.611000] scsi2 (0:0): rejecting I/O to offline device
The only difference in the two instances is the number of "commands" that are waiting to complete. This snippet above is from the first instance, the second instance had 10 commands waiting.
The machine is running the default Ubuntu kernel, which is their patched version of 2.6.12. In addition, both the megaraid_mbox and megaraid_mm modules are loaded. Here is an output of 'modinfo' for both of those modules:

I have contacted Dell - via their linux-poweredge mailing list - and have discovered that I am not the only one experiencing these problems. What bothers me is that while this problem, apparently, has been around a while and no fix has yet been discovered by Dell or anyone else.
My research also leads me to believe that this is not just an Ubuntu thing either. I have reports that this happens under Redhat, Debian and SuSE. It also appears as though the problem started happening around kernel version 2.6.9.
So, I'm hoping that someone here:
a). Knows about the problem and is working on it.
- and, more importantly -
b). Can lead me to a fix.
My machine is in production and I do not have any additional hardware to test with, but I can do limited testing with it as long as it is completely functional by 8:00 pm eastern time. I'm using it as offsite backup machine and that's when my backup processes kick in. If more information is needed, let me know how to get it, and I'll supply it.
I need to get this solved ASAP.
Thanks in advance,

Can you please try with following changes to seeif it works?
- configure the controller with 1 400GB RAID0 instead of 4 400GB RAID5
- 4GB (or less) memory
Also, please provide following information.
- F/W on the MegaRAID controller version
Thank you,

Hi all :)
I am wondering whether someone can shed some light on issues I am
having with LSI Megaraid cards ? The problem described below is with
SATA card, but I am also having difficulties with LSI HBA Scsi adaptor,
ableit I have not yet eliminated all the obvious things to try.
Please CC your replies as I am not on the list..
My setup: dual Opteron 252 with 8 GB RAM, Tyan Thunder K8W. SUSE 9.3 -
I tried both the native SUSE kernel and 2.6.14.3 from kernel.org, 4 400GB
Western Digital drivers in RAID5 configuration connected to LSI MegaRAID
SATA 150-6
The are also 3 250 GB drives connected to on-board SIL3114 where Linux
is installed.
Problem: card recognizes the disks fine, initialization goes ok.
I can create partition with no problem. However when copying files I get
filesystem corruption (holds both with ext3 and XFS). For ext3 I see the
following message:
EXT3-fs error (device sdd1): ext3_new_block: Allocating block in system zone -
block = 100663296
Aborting journal on device sdd1.
EXT3-fs error (device sdd1) in ext3_prepare_write: Journal has aborted
ext3_abort called.
EXT3-fs error (device sdd1): ext3_journal_start_sb: Detected aborted journal
Remounting filesystem read-only
The hardware is otherwise stable - this box also has 3 disks in software
RAID5 connected to SIL3114 and a similar box has 3ware card with 8 drives,
which function fine.
I would appreciate any suggestions on what to try/tweak/patch.
thank you very much !
Vladimir Dergachev
PS One more thing - none of LSI binary configuration tools work - they report
they cannot find the adaptor even though /dev/megadev0 is pointing to correct
adaptor (I tried both 253 and 254 for major numbers and 0,1,2,3,4 for
minor numbers). I was not successful in finding an open-source management
tool..

Hi,
I have a megaraid 466 controller, which both ami and the linux
kernel say is supported under 2.4.4, I tried the ami patches to
the drivers in the vanilla kernel to no avail, the card works
under windows...the card is even detected under linux now, but
it refuses to show any drives and i cant get the management
software to work. so my question is this:
has anyone with this card gotten it to work under linux
2.4.4-acX? if so, how?
I have read about many people upgrading firmware and using
'latest drivers' both of which i have done, so i am at a loss
here. any help is appreciated. --gabe
