I have a Raidz volume that I have noticed is running in degraded mode. It looks to me as if one of the drives has changed from
/dev/sde1 because the machine only has 3 WD RED 3tb drives whcih the RAID was built upon and the disk manager shows them as sda, sdb, and sde as shown in the picture below:
Is there a way I can fix the RAID array without having to wipe the /sde1 drive and rebuild the array which would take quite some time? To avoid this happening in future, do I need to avoid creating pools like so:
sudo zpool create -f [pool name] raidz /dev/sdb /dev/sdc /dev/sdd
and use UUIDs instead like this:
sudo zpool create -f [pool name] raidz \ "92e3fea4-66c7-4f59-9929-3a620f2bb24a" \ "92e3fea4-66c7-4f59-9929-3a620f2bb24b" \ "92e3fea4-66c7-4f59-9929-3a620f2bb24c"
