Hi all,
Are there any known issues of the raid1 resync not throttling properly?
I'm setting up a new array on a pair of SATA disks, and it hogs the
disks and blocks all
other i/o to them. If I lower /proc/sys/dev/raid/speed_limit_max
(before creating the array)
things run better, but that's not always an option -- I rebooted and the
system hung once
the resync started -- I had to pull the second drive to get things back
to normal.
This is on a 2.6.16.14 system, using mdadm 2.2 and 2.4.1. I've set up a
few mirrors
in the past with no issues, but those were all regular IDE. This is the
first time
I tried SATA. Are there any known SATA issues with RAID?
Does anyone have any thoughts on this?
TIA,
Bill
