--0000000000009e20d606097fb9ed Content-Type: text/plain; charset="UTF-8" I've been trying to get a zfs dataset delegated into a jail (to run PG on), and allow snapshots and rollback to take place inside the jail. I can get the dataset mounted into the jail, I can get zfs to take the snapshot, list the snapshot, but when I rollback or try to ls -la the directory to see the '.zfs' dir it isn't there and the zfs rollback completes but it doesn't actually rollback. I'm so close to getting this to work! I'm just missing *something* in the sauce. When I do the zfs rollback zfs looks like it completes the rollback and goes back to a shell prompt but the files I remove before the rollback are not in the /var/db/postgres/data16 directory nor is ".zfs" shown in ls -la. So something is wonky on my end. I'm so close, it's halfway there, it looks like it takes a snapshot, the snapshot shows up in a zfs list -t snapshot, but it's also not really there. I'm doing something just slightly wrong here. I just cant figure out what I have wrong. Below are the configs: # The jail's config https://bsd.to/P176 # zfs list from inside the jail https://bsd.to/mPde # zfs list -t snapshot from inside the jail https://bsd.to/R8dw # ls -la /var/db/postgres/data16 output from inside the jail https://bsd.to/1di2 # rc.conf of the jail https://bsd.to/JcnH The jail is running 13.2-P4. Using bastillebsd 0.10.20231013 for creation/management. Thanks!
