this is an old thread, but I cannot resist the urge to express my thanks to @fabian; your post literally saved my a.. ahem my day. Regards, Tony

I have a PVE cluster, where all nodes have a zfs pool with name `zpool`. I have a ZFS storage as follows (from /etc/pve/storage.cfg): zfspool: vm-disk-images pool zpool/vm-disk-images content rootdir,images mountpoint /zpool/vm-disk-images sparse 0 Recently I added a new node...

I have been keeping an eye on this container, and still could not figure out the cause of pagescan/swapout activities on this CT. I gave it 4G RAM and set swapiness=10 on the node, run `swapoff -a; swapon -a` on node. Any hint how to find out which process causes pagescan/swapout activities? I...

thanks for the hint. I read in this post that it seems possible to set swapiness for individual CTs but it's not confirmed by Proxmox yet. In my case atop reports swap activities, but vmstat does not. I am not sure if it's something to worry about. The small amount of used swap (8M) is really...

update: I'd like to reduce swapiness as recommended by some sources I could find, but it seems doing so requires a reboot of the CT, which I would like to avoid.

I have a CT that keeps swapping, despite having plenty free RAM. free -m total used free shared buff/cache available Mem: 3000 271 2194 0 534 2728 Swap: 1024 8 1015 I think the...

I gave (1) a try, but it seems running nfs-ganesha inside a LXC is not trivial. Anyone here has experience with this?

Hi, I need to setup a NFS server with continuous backup (for example every 5 min). Any suggestion how to do it please? At the moment I am considering these options: (1) LXC container with bind mount to a ZFS volume; NFS server via nfs-ganesha inside LXC, backup via ZFS snapshot on node (2) ZFS...

I am also very interested in running NFS Ganesha within a container. Anyone here has experience with this route? Can you please briefly share what you wish to know when you started?

in the past I used to run unfs3 on openvz CT and it worked ok, but now it seems unfs is not available from apt.

I want to setup a NFS server that would serve as shared home user dirs for a company. One requirement is that the data should be backed up continuously, similarly to dropbox (e.g. backup every 10min). I think it could be done with ZFS send/receive. I am considering 2 choices: (1) setup a CT...

thanks for your hint. I checked carefully and there is no env set. Then I tried again, and this time I got a password prompt on a PVE7 node. But not the 2nd try. So it seems the password is cached for sometime. I solved it as follows: crontab -l export...

thanks for the reply; in the end I went with the lxc.mount.entry method like in this thread

I tried proxmox-backup-client to backup a node to PBS; on a cluster with PVE 7 it didn't ask for password, but on a cluster with PVE 6 it did. Is it the expected behavior, or am I missing something? According to the pbs manual, a password prompt is to be expected.

I have some ZFS nested datasets on a node as follows: /zpool/ds1 /zpool/ds1/ds1A /zpool/ds1/ds1B when I bind mount /zpool/ds1 for a CT, the child datasets are not accessible in the CT. Is there a way to solve this, apart from having a separate bind mount for each ds1A, ds1B and so on?

thanks; I was hoping for some easier solution but running proxmox-backup-client on the node is ok, too.

update: in the end I decided to go with a VM; I am afraid that option (3) could cause problem on the node due to I/O problems. A VM provide better isolation from the node. But I still keep considering option (3), since it would allow continuously backup of the exported data via zfs send.

I already have a PBS configured for a cluster to backup the VMs/CTs. Can I use it to backup the node OS and cluster config? I searched the forum but didn't find any relevant post. thanks in advance for any hint.

thanks, I did the plan and it went well. I restored the CT to a different ID, since it's not possible to keep the old CT and new CT with same ID.

I have a PBS instance running inside a CT with bind mount /zpool/pbs,mp=/zpool-pbs on node-A in a PVE cluster. Is it possible to move this CT to another node-B in the same cluster without data loss? My plan is following: - backup the CT to local storage on node-A - copy backup to node-B - sync...
