I monitor all services listed in PVE HTTP GUI under System: After upgrade from 6 to 7 i got notifications about chrony not running. I installed chrony (replaced systemd-timesyncd) but now systemd-timesyncd failure is triggering monitoring system. As both can not run at the same time, I wonder...

+1 from me.

Hi, since we have installed ifupdown2 we can apply network configuration without restarting the host. What would the manual equivalent of this apply button be in shell? I tried ifdown vmbr0 && ifup vmbr0 and all VMs instances network cards were removed from the bridge and lost connectivity.

Will you open a bug report for us all?

Sometime wishes do not come true. :-)

Wish @mira would answer. :-/

@mira thank you for your suggestion. Please let me know if I understand it correctly. You suggest to resize both volumes (x 1.7 and x 2.4) and then move the volumes from ZFS to ext4? You say, newly created raw disk on ext4, which should have the exact size as the previous zvol (530 GB), is not...

It probably locks fs using qemu agent, but then fails to unlock it, due to some reason like unable to create snapshots, or whathever... If you just wish to get on with your life, you can try and disable qemu agent, as you will probably do not want to disable backups or replication.

Any update on this? @mira must more data provided for debugging, or? @Blipt i guess you will eventually have to do a manual rsync, as I did ....

If I remember correctly, it might have even crashed the server. If you want to commit less, just set max arc to less. Example echo 'options zfs zfs_arc_max="2147483648"' >> /etc/modprobe.d/zfs.conf echo 'options zfs zfs_arc_min="2047483648"' >> /etc/modprobe.d/zfs.conf update-initramfs -u I...

I will try and not set it on this new cluster. We'll see if it presents problems. :-) Opinions still wanted.

Didn't read whole thread, but if the LXC keeps consuming memory until OOM killer runs, in my experience was due to systemd logging into RAM. Do free -h before and after you run: journalctl --vacuum-size=15M and report back.

Well, depends on what you mean "better". For me personally it is not, It is slower and more complex in my experience. While you can not do true HA with ZFS (replication is scheduled), and it is quite slow, I prefer to use it for production as I really need the features it has. Also consider not...

Hi guys, ever since I have encountered a crash, because ZFS did not release ARC memory fast enough, I limit it's use to a number I know will always be available and will not be requested by other processes. I am wondering, is it safe now-a-days not to define maximum ARC size and ARC will...

Try SM or PM line of Samsungs SSDs; they have capacitors and will behave much much better. These desktop drives you are using are to slow for ZFS. If you choose (t)LVM and / or hardware raid, IO delay will come down, but not with ZFS.

Hi, on some network cards, vlans do _not_ work, unless I disable vlan aware bridge option. Because it always works, if I disable it, and I'm tired of testing this over and over, I wonder are there any downsides to not making bridge vlan aware and let PM create new bridge for every vlan. Do you...

Hi, when using PBS I noticed, that because of no dirty map for shut down VMs, PBS or PM vzdump does read whole VM to notice, that there are no changes. For shut down VMs with big disks, this means whole lot of disk reading for nothing. I would suggest, that a feature be implemented, that would...

We still have both of these these bugs a year later in pve-manager/6.3-6/2184247e. I guess we should open a bug report, if noone else has?

I guess you could open a bug report and force upgrade of drivers that way? Maybe we need to wait for Ubuntu to update in theirs and bumb should be made there. Anyway, open a bug report, i probably will do more than a forum post.
