Any ideas how to recover this HDD?

[jimmycheckers]

Hello,

Okay the long and short.

My HDD had a pool in it, I have determined that I had a bad SATA cable and it ruined a lot of my drives.

Long: I found this out because I swapped positions of my harddrives because one died, and now this second one has "died" it. This is the third time this has happened to me, before I couldn't figure out if it was bad drives or maybe user error. I turn the NAS on and off periodically to switch drives, I know it's not idea but it's what I am working with. I am in a panic because I really needed this drive because I was going to back it up. The good news is, unlike the other failed drives, this drive shows up, with the except that the pool that was set up in it is gone. Now I use two different boot drives of TRUENAS and it does not import the disk (cause the pool is obviously gone, and I backed up the truenas config once if that would even help. How, if possible, could I recover the pool of that zfs, or can I just save the data within it. I am not touching this drive until I've heard and explored every option as it is vital.

this appears to be a case of backups that aren't backups.

every time you mess about with the sata cables you risk damaging them or wearing the connectors out. you would be better off simply mirroring them; you would have no backup but at least your pool would be redundant and self healing.

a backup would be independent of these types of problems.

unless I have misunderstood, it sounds like you have rotated through and damaged every drive that had data on it, which would mean you have no data anymore.

explored every option as it is vital.

if there is no pool at all, there isn't really much to explore other than how to not have this happen again.

What is your pool's configuration? Just a single HDD? Was it previously a mirror? RAIDZ1/2/3?

Can you provide the relevant outputs?

Code:

zpool status -v

zfs list -r -t filesystem -o space
