Thank you for your advice and pointers. I looked further into that thread and others, and they helped to investigate the issue. Unfortunately, it seems (of course) that I have only succeeded in making the situation worse. The thread you linked to was indeed similar to my issue. I first looked into mdadm-grow-continue@md0.service, as suggested in http://www.spinics.net/lists/raid/msg49042.html : ______________________________________________ # systemctl status mdadm-grow-continue@md0.service ------------------------------------------------------------------------------- mdadm-grow-continue@md0.service - Manage MD Reshape on /dev/md0 Loaded: loaded (/usr/lib/systemd/system/mdadm-grow-continue@.service; static) Active: failed (Result: exit-code) since dim. 2015-09-20 16:48:15 PDT; 1 day 20h ago Process: 10989 ExecStart=/sbin/mdadm --grow --continue /dev/%I (code=exited, status=1/FAILURE) Main PID: 10989 (code=exited, status=1/FAILURE) ______________________________________________ The service was inactive, which was consistent with the fact that I didn't see any activity in top. I tried to re-start it, but the result was the same. Per http://www.spinics.net/lists/raid/msg49098.html , I commented out the StandardInput, StandardOutput and StandardError entries in the service file, and reloaded the daemon. This gave me these additional lines (bottom two lines of the output): ______________________________________________ # nano /usr/lib/systemd/system/mdadm-grow-continue@.service # systemctl daemon-reload # systemctl start mdadm-grow-continue@md0.service # systemctl status mdadm-grow-continue@md0.service ------------------------------------------------------------------------------- mdadm-grow-continue@md0.service - Manage MD Reshape on /dev/md0 Loaded: loaded (/usr/lib/systemd/system/mdadm-grow-continue@.service; static) Active: failed (Result: exit-code) since mar. 2015-09-22 13:03:26 PDT; 2s ago Process: 14688 ExecStart=/sbin/mdadm --grow --continue /dev/%I (code=exited, status=1/FAILURE) Main PID: 14688 (code=exited, status=1/FAILURE) sept. 22 13:03:26 mdadm[14688]: mdadm: Need to backup 5376K of critical section.. sept. 22 13:03:26 mdadm[14688]: mdadm: array: Cannot grow - need a spare or backup-file to backup critical section ______________________________________________ So apparently, the array couldn't be grown because there was no backup file originally specified. At that point, I figured I would stop the array and try to re-assemble it in its prior state. In retrospect, it was probably a bad idea, but I didn't realize at the time that stopping the array would be so problematic. I attempted to re-assemble using the "--update=revert-reshape" option as suggested in http://www.spinics.net/lists/raid/msg49596.html , but that didn't work: ______________________________________________ # mdadm --assemble --force --update=revert-reshape /dev/md0 /dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1 /dev/sdg1 /dev/sdh1 /dev/sdi1 /dev/sdj1 --backup-file=/root/backup.bak --invalid-backup --verbose ------------------------------------------------------------------------------- mdadm: looking for devices for /dev/md0 mdadm: /dev/sdc1 is identified as a member of /dev/md0, slot 0. mdadm: /dev/sdd1 is identified as a member of /dev/md0, slot 1. mdadm: /dev/sde1 is identified as a member of /dev/md0, slot 7. mdadm: /dev/sdf1 is identified as a member of /dev/md0, slot 6. mdadm: /dev/sdg1 is identified as a member of /dev/md0, slot 2. mdadm: /dev/sdh1 is identified as a member of /dev/md0, slot 3. mdadm: /dev/sdi1 is identified as a member of /dev/md0, slot 4. mdadm: /dev/sdj1 is identified as a member of /dev/md0, slot 5. mdadm: :/dev/md0 has an active reshape - checking if critical section needs to be restored mdadm: Cannot read from /root/backup.bak mdadm: Failed to find backup of critical section mdadm: continuing without restoring backup mdadm: added /dev/sdd1 to /dev/md0 as 1 mdadm: added /dev/sdg1 to /dev/md0 as 2 mdadm: added /dev/sdh1 to /dev/md0 as 3 mdadm: added /dev/sdi1 to /dev/md0 as 4 mdadm: added /dev/sdj1 to /dev/md0 as 5 mdadm: added /dev/sdf1 to /dev/md0 as 6 mdadm: added /dev/sde1 to /dev/md0 as 7 mdadm: no uptodate device for slot 16 of /dev/md0 mdadm: added /dev/sdc1 to /dev/md0 as 0 mdadm: failed to RUN_ARRAY /dev/md0: Invalid argument ______________________________________________ This was the output of mdadm -D afterwards: ______________________________________________ # mdadm -D /dev/md0 ------------------------------------------------------------------------------- /dev/md0: Version : 1.0 Raid Level : raid0 Total Devices : 8 Persistence : Superblock is persistent State : inactive Delta Devices : -1, (1->0) New Level : raid6 New Layout : left-symmetric New Chunksize : 128K Name : (redacted):0 UUID : eea59047:120a0365:353da182:6787e030 Events : 35500 Number Major Minor RaidDevice - 8 33 - /dev/sdc1 - 8 49 - /dev/sdd1 - 8 65 - /dev/sde1 - 8 81 - /dev/sdf1 - 8 97 - /dev/sdg1 - 8 113 - /dev/sdh1 - 8 129 - /dev/sdi1 - 8 145 - /dev/sdj1 ______________________________________________ dmesg provided some additional information, saying "reshape_position too early for auto-recovery": ______________________________________________ # dmesg | grep md ------------------------------------------------------------------------------- [164758.944492] md: bind<sdd1> [164758.944819] md: bind<sdg1> [164758.944977] md: bind<sdh1> [164758.945152] md: bind<sdi1> [164758.945339] md: bind<sdj1> [164758.945472] md: bind<sdf1> [164758.945610] md: bind<sde1> [164758.945785] md: bind<sdc1> [164758.952353] md/raid:md0: reshape_position too early for auto-recovery - aborting.

The signs look very similar. I have a version of mdadm --examine before stopping the array, and one of it now (both are posted at the end of this message). I've also posted a diff at https://gist.github.com/gpaumier/da3200b357f35288021d/revisions to make it easier to see the differences. As far as I can tell, the only difference is the additional disk I initially tried to add to the array. When trying to re-assemble, mdadm complained that that disk (/dev/sdb1) had a different superblock ("mdadm: superblock on /dev/sdb1 doesn't match others - assembly aborted") so I left it out when trying to re-assemble. I now realize (per http://www.spinics.net/lists/raid/msg49090.html ) that I should have tried to manually do "mdadm --grow --continue" with an empty backup file before stopping the array, unfortunately that wasn't clear to me at the time. According to http://www.spinics.net/lists/raid/msg49669.html , my last option seems to be to re-create the array, which worked for the poster. However, that operation (described at https://raid.wiki.kernel.org/index.php/RAID_Recovery#Restore_array_by_recreating_.28after_multiple_device_failure.29 ) seems very dangerous so I wanted to ask again here before doing anything else. This is how I see the current situation: * The good news is that all the data and metadata still appear clean, so if I tread carefully I should be able to recover my array with no data loss (and then re-attempt to grow) * The bad news is that my only option at this point seems to be to try to re-create the array manually, which would basically cause all data to be lost if if doesn't work. I figure I have a 50% chance of restoring the array, and 50% chance of making it completely unusable. I'm not very comfortable with those odds, so I would appreciate if anyone had any advice regarding what to do now, and alternatives to manually re-creating the array, if there are any. Many thanks for your help. ______________________________________________ Appendix 1: Output of mdadm --examine /dev/sd[b-j]1 before stopping the array ------------------------------------------------------------------------------- # mdadm --examine /dev/sd[b-j]1 /dev/sdb1: Magic : a92b4efc Version : 1.0 Feature Map : 0x5 Array UUID : eea59047:120a0365:353da182:6787e030 Name : (redacted):0 Creation Time : Thu Aug 1 12:23:07 2013 Raid Level : raid6 Raid Devices : 9 Avail Dev Size : 7814033128 (3726.02 GiB 4000.78 GB) Array Size : 27349115136 (26082.15 GiB 28005.49 GB) Used Dev Size : 7814032896 (3726.02 GiB 4000.78 GB) Super Offset : 7814033392 sectors Unused Space : before=0 sectors, after=480 sectors State : clean Device UUID : bde6e5ab:5f4a56e9:10ad82fc:301d477b Internal Bitmap : -16 sectors from superblock Reshape pos'n : 0 Delta Devices : 1 (8->9) Update Time : Sun Sep 20 16:48:15 2015 Bad Block Log : 512 entries available at offset -8 sectors Checksum : 28369459 -
