I have linux software raid (RAID10),
md2 : active raid10 sda6(F) sdd5 sdc5 sdb6 390620160 blocks 64K chunks 2 near-copies [4/3] [_UUU]
which has degraded state. Can i start recovery operation without removing and adding back failed item of array?
I have already tryed to start the resync operation,
echo 'repair' >/sys/block/md2/md/sync_action
but it has no effect…
I have read in docs, that
echo 'recover' >/sys/block/md2/md/sync_action
do replace failed item of array with the hot spare disk. But what does it do, if i have not hotspare partition for this array?
