    [solved, not reproducible] Tape backup restore behaviour

    Hi Dominic, Thank you for your explanation and for replying to my question so quickly after I didn't have an update for a week! Do I understand correctly that a snapshot archive is a bundling of (a subset of) chunks from the chunk archive? In that case it is in line with my expectation /...

    [solved, not reproducible] Tape backup restore behaviour

    Hi Dominic, Sorry for not getting back any sooner. Backups are important, but sometimes life has no attention for that and throws urgent matters in the way ;-) I had to read that twice. Do I understand correctly that you mean this case: upon starting restore, a check is (now not) made, which...

    [solved by re-re-verify] All four snapshots in a backup fail re-verification, new snapshot fails verification as well

    Hi Chris & forum, Thanks for your explanation! Sorry for not getting back any sooner. I was writing a reply while checking and comparing logs when my graphics card crashed, losing my draft and 'research'. I'll try to edit this post tonight with some useful reply! <edit 10 days later> Sorry, I...

    [solved, not reproducible] Tape backup restore behaviour

    Hi dcsapak, Thanks again for helping me out! Yes, I did. The existing snapshot does not pass validation anymore, I hoped that by restoring from tape I would overwrite the broken chunk. ("all four snapshots fail verification", my other thread.) Do I understand correctly that tape restore will...

    [solved by re-re-verify] All four snapshots in a backup fail re-verification, new snapshot fails verification as well

    TL;WR: This must have been a one-off run-together of circumstances 4 snapshots of a backup failed re-verification 8 corrupt chunks in snapshot 1 running 5th snapshot backup while verifying 1-4 5th snapshot also fails verification 3 different chunks restore snapshot 1 from tape (2...

    [solved, not reproducible] Tape backup restore behaviour

    Hi all, TL;WR: I had a snapshot that failed verification Restore from tape did not correct any chunks On re-verification it turned out that the verification had incorrectly flagged a number of chunks as failed Lessons learned: use server grade hardware or exercise patience (ie, don't run...

    proxmox-tape : will setting --latest-only on a job destroy earlier snapshots? What about retention?

    Hi dcsapak, Thank you for your quick reply! I think it asnwered all my questions. Would you mind reading my rehash of your explanation, to see whether I understood correctly? Latest only Ok, so as long as I play according to the rules and if not playing with retention or manual deletion of...

    proxmox-tape : will setting --latest-only on a job destroy earlier snapshots? What about retention?

    Hi all, I'm on PBS 2.4.x. There is an external tape drive connected to the system, but it is not running 24/7 as I need change the tapes manually anyway. The result is that tape backups occur less frequently than planned in the job. So there is a bit of a backlog of un-taped backup snapshots...

    [SOLVED] Implication of ZFS 'copies=2' for fdisk

    Hi Stefan, Thanks a lot for the clear explanation, and sorry for not posting back any earlier. With the information in the bug report I understand why the space is calculated more than once, and why it is difficult to make the system solve the puzzle.

    Problem cant acces Proxmox via web

    The error from apt upgrade may not be related to your problem with the web front end, but it should not happen either. I would solve that issue anyway. I did not know which version of linux-firmware-free was supposed to be on your system, and thought: "Maybe the system is being upgraded to a...

    Problem cant acces Proxmox via web

    Did you 'upgrade' or 'dist-upgrade', or maybe 'full upgrade'? How new is 'practically new' :-) Do you know where to find apt sources, and how to have a look at them? (/etc/apt/sources.list) I am new to Proxmox, but I know that with the release of Proxmox6, the underlying Debian system went...

    [SOLVED] Implication of ZFS 'copies=2' for fdisk

    Hi all, I just started with Proxmox and the forum. My hardware is a lot simpler than most things I read about on the forum, still it manages to puzzle me. On initial installation I got a single SSD, on which I put ZFS in RAID0, ie., a single disk pool. I set copies=2, and had a root partition...
