Hello,
We've used disksuite for some time to mirror our local disks, but after
rebooting a system this morning I saw something I hadn't seen before.
It's a 280R running Solaris 8 with a recent patch cluster (kernel
Generic_117350-12). Before I rebooted metastat showed everything as
Okay, but after the reboot two of my metadevices started resyncing (/var
and /usr). They have now completed syncing and everything looks good
again, but I don't have much confidence in how things would work if we
had a disk failure. There are no unusual syslog messages.
Here's the metastat output of the two problem mirrors:
bash-2.03$ metastat d3
d3: Mirror
Submirror 0: d30
State: Okay
Submirror 1: d31
State: Okay
Pass: 1
Read option: roundrobin (default)
Write option: parallel (default)
Size: 20484288 blocks
d30: Submirror of d3
State: Okay
Size: 20484288 blocks
Stripe 0:
Device Start Block Dbase State Hot Spare
c1t0d0s3 0 No Okay
d31: Submirror of d3
State: Okay

Submirror 1: d61
State: Okay

d61: Submirror of d6
State: Okay

Any thoughts on this greatly appreciated.
Rich
