Hey I bought 2 new disks to be included in a big raid5 array. I executed: # mdadm /dev/md5 -a /dev/sdh1 # mdadm /dev/md5 -a /dev/sdi1 # mdadm --grow /dev/md5 --raid-disks=8 After 12 hours it stalled: # cat /proc/mdstat md5 : active raid5 sdc1[6] sdb1[7] sdi1[3] sdh1[2] sdg1[1] sdf1[0] sde1[4] sdd1[5] 1562842880 blocks super 0.91 level 5, 64k chunk, algorithm 2 [8/8] [UUUUUUUU] [===================>.] reshape = 98.1% (306783360/312568576) finish=668.7min speed=144K/sec Its been stuck at 306783360/312568576 for hours now. When i check the kernel log it is full of "compute_blocknr: map not correct". I guess something went really bad? If someone know what is going on or if someone know what i can do to fix this. I would really be sad if all the data was gone.
