I ran into this problem, too. After reading this thread and the bug report, I ended up with the solution suggested by comment #13 in the bug tracker: run ssh to each node to invoke vzdump.
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

Mem: 3000 271 2194 0 534 2728

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?
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...
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?
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.
