Now, this zpool is made of 3-way mirrors and currently 13 out of 15 vdevs are
resilvering (which they had gone through yesterday as well) and I never got
any error while resilvering. I have been all over the setup to find any
glitch or bad part, but I couldn't come up with anything significant.
Doesn't this sound improbable, wouldn't one expect to encounter other chksum
errors while resilvering is running?
I can't attest to chksum errors since I have yet to see one on my
machines (have seen several complete disk failures, or disks faulted
by the system though). Checksum errors are bad and not seeing them
should be the normal case.
Resilver may in fact be just verifying that the pool disks are
coherent via metadata. This might happen if the fiber channel is
flapping.
Regarding the dire fiber channel issue, are you using fiber channel
switches or direct connections to the storage array(s)? If you are
using switches, are they stable or are they doing something terrible
like resetting? Do you have duplex connectivity? Have you verified
that your FC HBA's firmware is correct?
Did you check for messages in /var/adm/messages which might indicate
when and how FC connectivity has been lost?
