A lot of time restauring VM backups

[LkS45]

Hey guys!



Well, from the "progress 100% read..." to "total bytes read..." i got more that 2h! And the vm backup is only 150gb;
Well, that is, it takes more or less the same time from 1% to 100% as it does for the "task ok" message.
The whole process took a total of 4 hours, with 2 hours from 1 to 100% and another 2 hours for "task ok".
I have this problem with all my servers on my cluster. No any error message only the "no such logical volume pve/data".

Thanks.

My question is: why does the task take another two hours to finish after reaching 100% completion?
Since theoretically it should finish when it reaches 100%.

IIRC, Proxmox waits for the writes to actually be written to the drive (fsync, flush, that kind of thing), when it's between progress 100% and total bytes. Sounds like half of the data is still in memory if that takes as long as getting to a 100%. Note that the percentage is about reads and not writes.
What make and model is the destination drive? Is it a SSD with QLC flash memory or is it a SMR HDD maybe?

You use a NVMe with only 20 MByte /s on read random 4k.
The NVMe heat up is to much 70 - 80 °C over the write process?
