Hi,
Indeed, here is what I had in terms of event count:
/dev/sda10: 81589
/dev/sdb10: 81626
/dev/sdc10: 81589
Then the following procedure worked quite straightforward:
--------------------------------------------------------------------------------
# mdadm --assemble /dev/md10 --verbose --force /dev/sda10 /dev/sdb10 /dev/sdc10
# mdadm --manage /dev/md10 --add /dev/sdd10
--------------------------------------------------------------------------------
And 6h+ later:
--------------------------------------------------------------------------------
# cat /proc/mdstat
Personalities : [raid1] [raid6] [raid5] [raid4]
md10 : active raid5 sdd10[3] sda10[0] sdc10[2] sdb10[1]
5778741888 blocks level 5, 64k chunk, algorithm 2 [4/4] [UUUU]
--------------------------------------------------------------------------------
Then I ran:
--------------------------------------------------------------------------------
# e2fsck -f -n -t -v /dev/md10
e2fsck 1.42.5 (29-Jul-2012)

--------------------------------------------------------------------------------
Does it look OK enough to launch the mount?
Regards and thanks for your help
