Hi,I have recently been handed a couple storage systems and an HPC that was built by some guys who took off for "greener" pastures. I am new to ZFS and gmultipath and have a few questions if anyone is willing to help.
For starters, I have a couple failed disks so I am trying to wrap my head around the entire system before I go ripping disks out.
I have a single pool called array that contains 8 raidz sets.When i run "zpool status" i get output about the pool and the raid sets. They are labelled raidz3-0, raidz3-1, raidz3-2..., and I assume that those are labels and not definitive proof that the set is raidz3. When I run "zpool list -v array", each set has the same title of "raidz3"
Question: Is the output of "zpool list -v array" the definitive proof that it is raidz3 or is that just another label?
A snippet of "zpool status" shows for example:
array DEGRADED 0 0 0
raidz3-0 ONLINE 0 0 0
multipath/disk1p1 ONLINE 0 0

Question 2: One of the failed disks showing at the bottom there, but should I be alarmed by some of the disks being displayed as multipath/diskXXp1 instead of a gptid address?
I have a few more questions but we can start with these, -Gary
