Hi,
Does dm-raid queue resyncs of multiple dm-raid1 arrays, if the underlying
block devices are the same?
Linux md has this feature, e.g.:
# cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] [multipath]
md1 : active raid1 sda2[2] sdb2[1]
943202240 blocks [2/1] [_U]
[====>................] recovery = 21.9% (207167744/943202240)
finish=20290.8min speed=603K/sec
bitmap: 1/8 pages [4KB], 65536KB chunk
md0 : active raid1 sda1[2] sdb1[1]
67108736 blocks [2/1] [_U]
resync=DELAYED
bitmap: 1/1 pages [4KB], 65536KB chunk
After some time investigating, I can't find it in dm-raid.
Please can someone tell me if this is implemented or not?
If it is implemented, where should I look to see it happening?
Thanks,
Richard.
