Hello guys! ive been running truenas for about 3 months and today i realized that my server was down. it was giving me a Kernel panic not sycing (wo_vap) implies (wo_vap->va_mode == S_IFCHR)
after some trobbleshoot i made a USB with truenas and got in the shell. i could not use zpool import -f only zpool import -o readonly=on -f and zpool status -v gave me this:
Thanks for the help, is there another way to delete the file instead of using zpool import -f? this command gives me a panic kernel and using zpool import -o readonly=on -f does not let me delete the file.
the reason for the SLOGS a mirrors on a non-redundant pool is inexperience. i would apreciate a better way to setup. i have 3 drives and i thought i could use the mirror for avoiding situations like this
Why did you even create a SLOG vdev? A mirror’s redundancy makes sense for your storage, not a secondary LOG. You can lose a SLOG, since it doesn’t contain irreplaceable data. You can’t afford to lose your actual storage pool.
Are you willing to start all over with a new pool? Does your current pool contain important data that you cannot lose?
inexperience, i really didn’t understood how to setup properly.
there is some data that i would like to keep, but i gonna try to use a Linux USB drive to move some data out of the NAS. but after that i don’t have any problem in starting over again.
to be honest its a good move to start over since the first time i was kind of stumbling to make it work, now i have some kind of experience and would like to set things properly
Just a update post and asking for help a new setup. after all is done i got a USB stick with Ubuntu live session and a external HDD imported my truenas data backup to the HDD and made a fresh install of the truenas OS.
Now i ask how to make a good zpool setup to avoid situation like this again. i have 2 HDD (4TB and 1TB )and 1 SSD( 250gb). how do i setup these drives?
There’s no recommended vdev configuration that you can do with those drives.
If you don’t want to wait, you could create a 2-way mirror with the 4TB and 1TB drives. This will give you a redundant pool with a capacity near 1TB. In the future you can purchase a new 4TB drive to replace the 1TB in the mirror, which will bring your capacity up to near 4TB.
I don’t see much use for your single 250GB SSD. You can create a single drive pool with it to use for temporary downloads or extra temporary space when doing migrations.
thank you for helping along the way, i think i’ll do a mirror then and read up more on snapshots for it. the posible ill buy another 4TB in the future
