I have a 6 x 4TB disk RAID RAIDz2
A couple of weeks ago one drive failed, took it out and sent to supplier, only to have another drive start giving unrecoverable errors a couple of days later. We replaced the original drive and started an import which did a scrub and completed 100%, however, upon looking at the logs I get:
I am making an assumption that the rebuild failed, and likely due to the 2nd drive giving unrecovable errors, but what I dont understand why all of the other drives are shown as degraded. I ran a smart test on the 1st one and it came back without any faults, so not sure what to do?
It does appear that I had some data loss as there are a large number of data missing, fortunately this is a backup of a backup so a lesson learnt (just not sure what lesson yet
)
What is my next steps? Does this simply mean the entire pool is degraded beyond repair? I again cannot imagine all 6 drives fail (and no, it's a IT mode HBA so not a raid controller)
