Re: [CentOS] variable raid1 rebuild speed?

I have a 750Gb 3-member software raid1 where 2 partitions are always

The timing of

the resync seems to be extremely variable recently, taking anywhere from

3 to 10 hours

even if the partition is unmounted and the drives aren't doing anything

else and

regardless of what I echo into /proc/sys/dev/raid/speed_limit_min or

_max. Is there

some way to tell if the drives are going bad or speed it up consistently

if they aren't?

Only thing I can think is if there's a lot of activity on the disks, with many, many gigs of files added or deleted.
