Hi, Software RAID is driving me mad on various RHEL5 servers (mostly updated to 5.6, probably running 5.5 kernels still).
Here's a clear example : [root@x5i01 ~]$ cat /sys/block/md2/md/mismatch* 384 [root@x5i01 ~]$ echo repair > /sys/block/md2/md/sync_action [root@x5i01 ~]$ watch cat /proc/mdstat [root@x5i01 ~]$ cat /sys/block/md2/md/mismatch_cnt 2560 [root@x5i01 ~]$ echo check > /sys/block/md2/md/sync_action [root@x5i01 ~]$ watch cat /proc/mdstat [root@x5i01 ~]$ cat /sys/block/md2/md/mismatch_cnt 4736 Initially I receive a cron.weekly email about "WARNING: mismatch_cnt is not 0 on /dev/md2", which is why I go ahead and force a repair, then force a check. It gets worse after every step, and each of those two operations takes hours (750GB SATA disks). What am I doing wrong? This particular copy/paste comes from a server running 2.6.18-194.el5xen x86_64.
