Hello everyone,

Faced such problem - paths to disks and general any symbols disappeared in backup task, backup is simply created incomprehensibly and is written to nowhere, Proxmox VE version has been updated to the latest version. /etc/pve/vzdump.cron & /etc/vzdump.conf files didn't change.
now it looks like this:
Code:
INFO starting new backup job vzdump 115 --node server --storage sata2 --compress lzo --mode suspend --remove 0

before the update it was like this:

Is there way change any file backup task, without installation successful backup? Just need to fix this structure, but I don't know how (
 
Hi,
please provide the output of pveversion -v. You might also want to use the debsums tool to verify the installed files. Do you get the same behavior when you start the backup manually from the command line (just copy the command from the first line in the log)?

Hello, what's strange if i make backup manually behavior is different:

tried to find debsums tool, but my searches were unsuccessful - tool itself is not there, i don't exclude that missed something, all that found was algorithms for checking files separately like sha224sum

What if you open the task log in the UI afterwards (even if you start a job manually, the task log should show up)? Is this a stand-alone node or is the request proxied to another node in the cluster?

It has to be installed first with apt-get install debsums. I suggest running
Code:
debsums -s pve-manager libpve-guest-common-perl libpve-common-perl proxmox-widget-toolkit
for likely culprits (or simply debsums -s for everything). If there is no output the installed files should be fine.

1. Yes, there's always log.
2. have 1 server, stand-alone node
3. no output for debsums -s and
Code:
debsums -s pve-manager libpve-guest-common-perl libpve-common-perl proxmox-widget-toolkit
 
1. Yes, there's always log.
Does the log of the task started via CLI have the special symbols when you view it in the UI?

package update came, after that it all appeared, checked - all paths are in place, only backup is carried out for very long time in 2 hours 1%, before this was not what happens. I stopped understanding anything :D

Code:
INFO: starting new backup job: vzdump 115 --compress lzo --quiet 1 --all 0 --node server --storage sata2 --mode suspend --mailnotification always

Did hardware raid 1 on ssd, all disks are working in normal, backups don't differ much now backup should weigh 420-430 gigabytes, but before 2.7 terabytes was processed maximum of 2 hours, now only 1% in 2 hours, it's weird that he's so slow, i run backup at night, when there is no load on server and there are 5 hours for backup but maximum 3% was processed in 5 hours

Are there any interesting messages in /var/log/syslog? Could you try booting with an older kernel and see if the speed is better?

1) The only thing that was interesting in log:
Code:
Oct 21 05:43:39 server pveproxy[1519]: worker 31726 finished
Oct 21 05:43:39 server pveproxy[1519]: starting 1 worker(s)
Oct 21 05:43:39 server pveproxy[1519]: worker 38696 started
Oct 21 05:43:39 server pveproxy[38695]: got inotify poll request in wrong process - disabling inotify

otherwise all tasks completed successfully

2) unfortunately can't make backup to older kernel, this server works 19 hours day even on weekends, there are several databases, u know
making backup remotely is not good idea.

3) tried to put other disks - this also didn't work + result of command:
Code:
debsums -s -a
debsums: changed file /etc/issue (from base-files package)
