* Failed --grow. Recovery possible? [not found] <959332b61003181836jea0d170jf6163e4ab81376f8@mail.gmail.com> @ 2010-03-19 1:52 ` Stephan Stachurski 2010-03-19 1:57 ` Stephan Stachurski 2010-03-19 4:02 ` Neil Brown 0 siblings, 2 replies; 6+ messages in thread From: Stephan Stachurski @ 2010-03-19 1:52 UTC (permalink / raw) To: linux-raid I have had a RAID5 up for quite a while with 6 disks. I recently added 4 and attempted to grow the array to span all 10 devices. For an hour after starting the grow command, the speed of the operation was 0K/s the entire time. I thought something must be wrong, and the best course of action would be to reboot and start over from a clean boot. I'm not a linux expert so I thought that if I rebooted everything would try to exit gracefully. After one hour, the system still had not finished shutting down. I then did alt-sysreq RSEISUB waiting over one minute between each command. I've included the syslog of what happened up until the next start up, but put it last because it's by far the longest. When I rebooted, the array seemed to be up, but mounting it resulted in a bad FS type error, even when I tried to specify it (ext4). After stopping the inactive array, and trying to reassemble it, mdadm crashed to segmentation fault. Is it possible to recover the data? We have backups, but they're spread out over 1500 DVDs. When I examine the drives, the output looks pretty much like this for each drive (6 drives say active and 4 say clean, corresponding to the 6 original and 4 added drives): $ mdadm --examine /dev/sda /dev/sda: Magic : a92b4efc Version : 00.91.00 UUID : 56c16545:07db76d6:e368bf24:bd0fce41 Creation Time : Tue Feb 2 09:58:58 2010 Raid Level : raid5 Used Dev Size : 976762368 (931.51 GiB 1000.20 GB) Array Size : 8790861312 (8383.62 GiB 9001.84 GB) Raid Devices : 10 Total Devices : 10 Preferred Minor : 0 Reshape pos'n : 0 Delta Devices : 4 (6->10) Update Time : Thu Mar 18 23:33:40 2010 State : active Active Devices : 10 Working Devices : 10 Failed Devices : 0 Spare Devices : 0 Checksum : 79904299 - correct Events : 270611 Layout : left-symmetric Chunk Size : 256K Number Major Minor RaidDevice State this 4 8 0 4 active sync /dev/sda 0 0 8 16 0 active sync /dev/sdb 1 1 8 96 1 active sync /dev/sdg 2 2 8 112 2 active sync /dev/sdh 3 3 8 48 3 active sync /dev/sdd 4 4 8 0 4 active sync /dev/sda 5 5 8 32 5 active sync /dev/sdc 6 6 8 160 6 active sync /dev/sdk 7 7 8 144 7 active sync /dev/sdj 8 8 8 128 8 active sync /dev/sdi 9 9 8 80 9 active sync /dev/sdf #syslog showing how mdadm detects the bad 10-drive array on boot Mar 18 23:47:35 raidserver kernel: [ 2.178393] md: bind<sdc> Mar 18 23:47:35 raidserver kernel: [ 2.193132] md: bind<sdd> Mar 18 23:47:35 raidserver kernel: [ 2.211906] md: bind<sdb> Mar 18 23:47:35 raidserver kernel: [ 2.220062] md: bind<sda> Mar 18 23:47:35 raidserver kernel: [ 2.230062] ohci1394: fw-host0: OHCI-1394 1.1 (PCI): IRQ=[22] MMIO=[fd6ff000-fd6ff7ff] Max Packet=[2048] IR/IT contexts=[4/8] Mar 18 23:47:35 raidserver kernel: [ 3.551483] ieee1394: Host added: ID:BUS[0-00:1023] GUID[003635c7006cf049] Mar 18 23:47:35 raidserver kernel: [ 6.579349] /build/buildd/linux-2.6.31/drivers/scsi/mvsas/mv_sas.c 1214:port 0 attach dev info is 0 Mar 18 23:47:35 raidserver kernel: [ 6.579353] /build/buildd/linux-2.6.31/drivers/scsi/mvsas/mv_sas.c 1216:port 0 attach sas addr is 0 Mar 18 23:47:35 raidserver kernel: [ 6.780038] /build/buildd/linux-2.6.31/drivers/scsi/mvsas/mv_sas.c 1214:port 1 attach dev info is 0 Mar 18 23:47:35 raidserver kernel: [ 6.780041] /build/buildd/linux-2.6.31/drivers/scsi/mvsas/mv_sas.c 1216:port 1 attach sas addr is 1 Mar 18 23:47:35 raidserver kernel: [ 6.990054] /build/buildd/linux-2.6.31/drivers/scsi/mvsas/mv_sas.c 1214:port 2 attach dev info is 0 Mar 18 23:47:35 raidserver kernel: [ 6.990057] /build/buildd/linux-2.6.31/drivers/scsi/mvsas/mv_sas.c 1216:port 2 attach sas addr is 2 Mar 18 23:47:35 raidserver kernel: [ 7.200052] /build/buildd/linux-2.6.31/drivers/scsi/mvsas/mv_sas.c 1214:port 3 attach dev info is 0 Mar 18 23:47:35 raidserver kernel: [ 7.200055] /build/buildd/linux-2.6.31/drivers/scsi/mvsas/mv_sas.c 1216:port 3 attach sas addr is 3 Mar 18 23:47:35 raidserver kernel: [ 7.310035] /build/buildd/linux-2.6.31/drivers/scsi/mvsas/mv_sas.c 1214:port 4 attach dev info is 0 Mar 18 23:47:35 raidserver kernel: [ 7.310038] /build/buildd/linux-2.6.31/drivers/scsi/mvsas/mv_sas.c 1216:port 4 attach sas addr is 0 Mar 18 23:47:35 raidserver kernel: [ 7.420035] /build/buildd/linux-2.6.31/drivers/scsi/mvsas/mv_sas.c 1214:port 5 attach dev info is 0 Mar 18 23:47:35 raidserver kernel: [ 7.420038] /build/buildd/linux-2.6.31/drivers/scsi/mvsas/mv_sas.c 1216:port 5 attach sas addr is 0 Mar 18 23:47:35 raidserver kernel: [ 7.630052] /build/buildd/linux-2.6.31/drivers/scsi/mvsas/mv_sas.c 1214:port 6 attach dev info is 2000000 Mar 18 23:47:35 raidserver kernel: [ 7.630055] /build/buildd/linux-2.6.31/drivers/scsi/mvsas/mv_sas.c 1216:port 6 attach sas addr is 6 Mar 18 23:47:35 raidserver kernel: [ 7.840053] /build/buildd/linux-2.6.31/drivers/scsi/mvsas/mv_sas.c 1214:port 7 attach dev info is 0 Mar 18 23:47:35 raidserver kernel: [ 7.840056] /build/buildd/linux-2.6.31/drivers/scsi/mvsas/mv_sas.c 1216:port 7 attach sas addr is 7 Mar 18 23:47:35 raidserver kernel: [ 7.840062] scsi8 : mvsas Mar 18 23:47:35 raidserver kernel: [ 7.840605] /build/buildd/linux-2.6.31/drivers/scsi/mvsas/mv_sas.c 380:phy 0 byte dmaded.

It won't be trivial, but it should be possible. I looks like the driver for the mv_sas controller has issues. When md/raid5 started writing data on to them to reshape the array something went wrong and the writes didn't complete, so nothing else happened. I don't know why mdadm is getting a segmentation fault. Possibly this is fixed in a newer version of mdadm. However it is possibly good that it didn't manage to restart the array fully as it would probably has just failed again and might have made more of a mess. To get you data back we need to understand exactly what happened. What should happen when you run "mdadm --grow ... " is that it sets up for a reshape but doesn't let it progress. Then it prints: mdadm: Need to backup 1152K of critical section.. It then copies the first 1152K (in the case of 6->10 with 256K chunk) from the start of the array to near the end of each of the 'spares'. Then it allows the reshape to proceed. Once the reshape has progressed past that 1152K it removes the copy that it made (erases some metadata for it) and prints mdadm: ... critical section passed. I presume that it didn't successfully pass the critical section, else the Reshape Position would be greater than 0. It is possible that the reshape didn't start at all and your data is exactly where you left it, but we cannot be sure without looking... What I suggest you do is: 1/ find the backup of the first 1152K 2/ re-create the array as the original 6-drive raid5 3/ Check if the backup needs to be restored and possibly restore it 4/ Don't use the new drives until you are really sure they will work. 1 is the hardest. I have a vague plan of giving mdadm the ability to do this but I haven't yet. I could possibly do it next week some time if you can wait. You would need to look at the code in Grow.c to see where it is written. I think there is a block of metadata near the end of the device - just before the md metadata - which records what has been backed up where. Once you find and decode that from one of the spares you can easily use 'dd' to extract the backup. 2 is quite easy: mdadm -C /dev/md0 -e 0.90 -l 5 -n 6 -c 256 \ --assume-clean /dev/sdb /dev/sdg /dev/sdh /dev/sdd /dev/sda /dev/sdc Make sure you have the devices if the right order. If you aren't sure, then mdadm -E list..of..devices | grep this should give you an ascending series in columns 2 and 5. 3 is simply a 'cmp' between /dev/md0 and the backup that you restored. or maybe just 'fsck' of /dev/md0. If you decide to restore (be sure before you do), just dd the backup to the start of /dev/md0 I don't know how you can make yourself sure that the drives really do work. Lots of testing of the new devices by themselves in an array ??? Good luck.

* Re: Failed --grow. Recovery possible? 2010-03-19 4:02 ` Neil Brown @ 2010-03-23 19:53 ` Stephan Stachurski 2010-03-23 21:07 ` Michael Evans 0 siblings, 1 reply; 6+ messages in thread From: Stephan Stachurski @ 2010-03-23 19:53 UTC (permalink / raw) To: linux-raid Sorry, it looks like I sent two replies directly to NeilBrown instead of the mailing list. Here they are: First reply: Before I checked this email, I upgraded to the newest version of mdadm on advice I got from #linux on freenode. The array is no longer segfaults when it's assembled. Instead it picks up exactly where it left off trying to grow the array but not actually progressing. In the new version of mdadm, however, after a short while the drives on the mv_sas controller are dropped and mdstat reports that a resync is pending. This looks like an improvement to me. I am going to try to test out the controller and drives to see if I can find out what's going on. ---------------------- Second reply: I hope I haven't screwed up my disks beyond saving. I was using this earlier question on the mailing list as a reference http://www.mail-archive.com/linux-raid@vger.kernel.org/msg08907.html . If I could re-assemble the original array, I would feel a lot more comfortable proceeding. In the above referenced thread, Greg Nicholson mentions that order matters when it comes to assembling arrays, so I wrote a perl script (full of terrible hacks) that took the list of the 6 original devices and iterated over the permutations of the order of those devices, assembled the array with --assume-clean and attempt to mount the file system. This failed for all 720 permutations. It was probably a stupid idea, anyway... I also tried plugging in a known working disk into the mv_sas controller that may have had an issue and it looked like everything was working OK. Now I'm really not sure what to do. I'm completely lost. Thanks again for your help.

Your array has entered a less than known state; likely while working with the critical section. Some parts may be stored as before, while others may be stored as things should look now. This is why the critical section backup and possible recovery is very important. Please follow Niel Brown's directions /very/ carefully. You probably also want to save the start of each device. dd if=/dev/container of=someplace/array_dev_X.raw bs=1024k count=64 for each device in the array (saving to separate files) would probably be a tolerable safety net to start with. You could also load these much smaller segments in hex-editors more easily. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html ^ permalink raw reply [flat|nested] 6+ messages in thread

The only thing I am sure of is number 4 that the new drives work. I have tested them individually in the same controller and they're working fine. 1 - "You would need to look at the code in Grow.c to see where it is written" The last time I have looked at C code was over ten years ago when I was 15 years old. I wish I would have become a kernel hacker instead of a lowly web developer, but this isn't my area of expertise. Grow.c is a huge file it's quite daunting. I don't even know what I could hope to learn from this data once I find it. 2 is not quite easy. I've re-created the original array (in the order that I'm 99% certain the original array was) and no attempt to mount or check a file system there will work. There must be something between step 1 and 2 where I have to restore the "critical section" to a certain spot, maybe?
