    Moving container on LVM thin volume to smaller storage

    Thanks again! pkill fstrim runtime less than a second, no output pct unlock 104 slight pauze, ok with no output PVE had a as stale mount of the volume in /var/lib/lxc/104/roofs, manually unmounted pve fsck 104 ran less than a minute, states "clean" lvresize -tvr -L 400G...

    FC SAN cluster in proxmox

    Hi n10ev, Welcome to the forums! While it's not my place to answer for nbaniks situation: if they're migrating from an existing VMWare deployment, the hardware is already in place. Replacing (high cost) fibre channel equipment with (lower, but still high cost for performance) ethernet...

    FC SAN cluster in proxmox

    In addition to the answers to your specific question, seeing you joined a while back but did not post a lot here: for many "is ... supported" questions, it is good to realize that Proxmox runs on top of Debian. Even if Proxmox does not provide a direct interface, if it is supported on Debian...

    Severe kernel panics are occurring

    The screenshot is to small to easily read or copy/paste, so it may totally not be related, but not mentioned is everyone's nr 1 checkpoint (memtest), and what kind of memory you run. I suppose it's ECC (because Ryzen/ZFS), but Asus shouts "Overclocking FTW".

    two node setup with local Dell R600 series storage with replication

    Hi mws, Welcome to the forums! As with many things, there is not one 'correct', and mostly 'it depends'. I've always been very happy LVM, and with thin volumes as well. ZFS is beckoning, but for better or worse, I have resisted the call. Even though ZFS is no 'must to do', there are very...

    MP on LXC is not coming through

    Your post is a bit old, sorry for the late reply... Yes, mount the NFS on the host, and bind-mount in the container

    Moving container on LVM thin volume to smaller storage

    Shortly after I had the opportunity to log in and kick off the fstrim, than realized it would be handy to chain fsck: # pct fstrim 104 ^C # pct fstrim 104 && pct fsck 104 CT is locked (fstrim) It's nine hours later now. I realize that fsck wouldn't have worked out on the running container...

    I cannot make a proxmox cluster with msi z790 motherboard.

    Oh, my bad, I mixed up your hostnames while zooming in and out of screenshots and trying to remember the names in the mean time. On pvebig: echo '10.201.3.215 pveraider' >> /etc/hosts and on pveraider echo '10.201.3.192 pvebig' >> /etc/hosts

    Moving container on LVM thin volume to smaller storage

    Hi Impact, Great! Thank you for mentioning, I was under the impression (as you probably guessed) that the LV itself was grow-only as well. I'm at the moment not able to test it right away, but I'll post feedback after I tried!

    Moving container on LVM thin volume to smaller storage

    The following step was unexpectedly successful, I had expected to wait a day for 3 TB to be backed up, but to my surprise the backup was already finished. It had actually only processed data for the size of the file system, not for the size of the partition. That's a bonus in my eyes ;-) Step...

    I cannot make a proxmox cluster with msi z790 motherboard.

    It seems more of a network (-configuration) issue, than BIOS/hardware. I wouldn't put my hosts in the 'example.com' domain, but it won't hurt in this case either I suppose. Some thoughts after seeing the actual error, 'hostname loockup 'pveraider' failed: Does your network provide DNS for...

    Moving container on LVM thin volume to smaller storage

    Update, unexpected failure at step 1, While logged in to the host, with the container shut down, I resized the FS in the LV to 600 GB: # fsck.ext4 /dev/mapper/allerlei-vm--104--disk--0 e2fsck 1.47.0 (5-Feb-2023) /dev/mapper/allerlei-vm--104--disk--0: clean, 5198085/244908032 files...

    I cannot make a proxmox cluster with msi z790 motherboard.

    Hi, more questions: "Same network": you mean they are connected to the same switch, or at least in the same VLAN or broadcast domain? "am at machine A" : you mean, you log in to the GUI at https://a:8006 ? "Can login to machine A...": again, log in to the GUI, or SSH? "... cannot go to shell...

    I cannot make a proxmox cluster with msi z790 motherboard.

    Hi onam, To get the terminology right, you mean cluster as in: "I can manage node A when logging in to node B, and vice versa", not the specific combination of nodes into a HA-cluster, correct? Either way, as far as I'm aware, clustering is purely network / configuration dependent, not...

    Moving container on LVM thin volume to smaller storage

    Hi all, I have a container on a thinly provisioned LVM volume. I want to extract the disk that backs the thin volume out of the system running Proxmox, but run into the issue that thin volumes don't support shrinking. After moving stuff out of the way, there is a lot of air in the container...

    Optimizing PVE containers for backup / storage tiering

    To make this more concrete, and perhaps elicit some speculation about the pros and cons, this is how I plan to set up the constellation: PVE node runs seven containers: yunohost: runs, among others Nextcloud nc2000 : stores data up to and including the year 2000 nc2010 : stores data up to and...

    Tape-Backup für Anfänger

    Meiner Erfahrung nach, scheitert der backup Task als es im Pool keine leere Tape gibt wann PBS ein neue Tape braucht. Das ist aber einige Jahre her, seitdem mach ich mich sicher, dass es genugende (beschreifbare) Tapes im Pool gibt.

    Wait for new tape when no more available

    My 'solution' is to over-allocate tapes in the pool, which is not optimal: I create temporary labels that I attach with tape (sticky tape, that is...), so they're easily removed to either replace with permanent stickers (if used) or I take them off and apply another temporary label if it goes to...
