Platform: ubuntu 10.10, kernel 2.6.35-30-server (yes I know it's old - update to 12.04 is scheduled) RAID6 array md1 was running as degraded with two failed disks, sdg and sdk. I did a dd write of zeros across both disks, which was successful, so re-introduced them into the array. I also enabled scterc, which hadn't been enabled before. However some hours into the rebuild, sdg failed again. Now the RAID rebuild has stuck at the following point: cat /proc/mdstat ... md1 : active raid6 sdk[6] sdg[5](F) sdm[0] sdf[2] sdl[1] 8790786048 blocks super 1.0 level 6, 16384k chunk, algorithm 2 [5/3] [UUU__] [================>....] recovery = 82.1% (2408361728/2930262016) finish=2976485.1min speed=2K/sec If I repeat cat /proc/mdstat, even after several minutes, the values do not increment. The last ~400 lines of dmesg are below. Key items are: 22440448.503388 - sde added to md0 (this array is now fine) 22440458.737931 - sdg added to md1 22440460.941412 - sdk added to md1 22542378.442924 - sdg started to fail, corrected read errors 22581985.862037 - sdg kicked out, uncorrectable errors 22581986.111914 - "recovery done"!! So mdstat says that recovery is ongoing, when clearly it isn't. I'm not sure what I should do next. Should I just hot-swap sdg, or should I reboot to clear the stuck /proc/mdstat status? Thanks, Brian.
