Maybe it’s trying to import the pool, using the failed drives? (Unlike when you used the command-line with the -f override.)
Assuming sdn is one of the failed drives.
I tryed to creat a share but get an error
I cant create any more replys as for 22 hours as this is a new account
Edit 2:
looks like the datasets are nolonger showing, the pool is and has 25 days to resilver
edit 3:
im shutting down the system as I dont want a resilver to mess with any data that could still be recoverd
Im going to try a ubuntu iso to try and mount the pool in read only and copy it to a local hdd
Not my wheelhouse but I think that may not have been necessary, assuming the command equates to -o altroot=/mnt
Just out of curiosity / to learn myself: As I see it both vdevs are degraded (with two failed drives each), the pool itself should be able to come online as indicated by zpool status.
So I would assume your not completely out of luck right now.
Does your last screenshot indicate the pool was successfully imported?
Do you mean you did not see datasets in the GUI or in your shares?
@ericloewe any chance you can bump priv?
Yes -R /mnt is equivalent to cachefile=none, altroot=/mnt
After importing the pool as read-only, best thing to do would have been to confirm that data was accessible and mounted by checking /mnt/ - anything super critical you’d want to copy off via SFTP before troubleshooting further - lest anything go kaboom.
Should be better now.
I was able to mount the pool using zpool import -f -o readonly=on -R /mnt Tank
Then using SFTP over SSH and filezilla I was able to connect to the pool and start copying the critical data off
Just got to hope it holds together until I get the data off that I need
The next thing is finding the root cause and then rebuilding.
I’ve ordered a synology nas to set up as a backup so that I don’t have this happen again without a backup of my critical files
I’ve still got a long way to go but it’s looking positive
You should be ok as there are two disk failures, which RAIDZ2 is tolerant up to.
What you’ll need to do after you’ve got this copied off is figured out why this replacement process isn’t working properly.
I don’t know where to even start troubleshooting.
I believe it has something to do with the LSI 9305-24i I have been using, I bought 2 cards from the same ebay seller. and I have had similar problems with each.
I ordered 2 LSI 9305-16i from a different seller to try my luck (since this is the model that 45 drives uses)
All cards where preflashed in IT-mode
I dont know where to start looking for the root cause
