[parisc-linux] UreStoreOptical 20xt

[Arnaud.ATOCH]

First thank you for the port. I'm running a 712/100 with no special trouble
(iso image 0.9.2).

I've got 1 question on the HP Surestore Optical 20xt.

I was using this robot on HP-UX. It is now connected to the 712/100. It is
seen by the SCSI driver and using mtx, I can load, unload, eject opticals
disks.

Using fdisk, I can partition, format (mkfs),and then use blank optical
drives.

I'd like to read all ones created with HP-UX.

I know that sector size of 1024 is no more an issue since 2.2.16 or
something but neither mount or fdsik recognize what's on the drive for HP-UX
written disks.

I've loaded hfs, hpfs, udf, ufs because it was not clear which module
provide HP-UX filesystem support.

Btw does the HP-UX fs support patch made it to Linus tree ?

thanks for any feedback.

IIRC, should only need hpfs (which also depends on ufs?..dunno anymore)
hfs == Apple's Hiearchial File System.

dunno.  But didn't that patch come from the parisc-linux tree?

Anyway...you might check if those disks are under LVM control.
If so, you'll have to convert those to non-LVM storage using HPUX.
The archives for parisc-linux mailing list have a discussion on HP's
LVM issues.

BTW, You might also try to explicitly specify the hpfs type.

hpfs is IBM's High Performance FileSystem for OS/2 :-)
You need ufs and mount with -ohp, iirc.

Yes, it's in Linus' tree.  We merged that in a loooong time ago.

That's what I assume.  There is now vxfs support in the tree, but nobody's
tried getting it working on HP vxfs volumes.  Volunteers...?

oops...thanks for the correction and -ohp is right:

grundler <520>fgrep -i hp fs/ufs/*
fgrep: fs/ufs/CVS: Is a directory
fs/ufs/super.c: * HP/UX hfs filesystem support added by
fs/ufs/super.c:                 else if (!strcmp (value, "hp"))
fs/ufs/super.c:                         ufs_set_opt (*mount_options, UFSTYPE_HP);
...
fs/ufs/super.c:                 printk(KERN_INFO "ufstype=hp is supported read-only\n");


BUG: Documentation/filesystems/ufs.txt doesn't mention -ohp

Ooh..it's possible those optical disks ended up using vxfs too...
and CONFIG option says that's RO support too.

Ok, thanks for coming back .

I've learn a lot and here are my conclusions :

- hpfs is OS/2 specific.
- The HP-UX fs patch came from parisc tree and did it into Linus tree
(2.4.8).
- HP-UX fs support in in the ufs module.
- Correct syntaxe for mount an HP-UX fs under Linux is : mount -t ufs -o
ufstype=hp /dev/sda /mnt/opti
- LVM fs are not so easy to handle and for now no success.

So the HP Surestore Optical 20xt is fully functionnal under Linux parisc or
x86.

Again thanks for you excellent work.
