But... same node, different vm:
INFO: 100% (64.0 GiB of 64.0 GiB) in 5m 40s, read: 508.0 MiB/s, write: 4.0 MiB/s
INFO: backup is sparse: 56.17 GiB (87%) total zero data
No changes, except for restore that now works; this is the same vm very slow in backup:
progress 100% (read 64424509440 bytes, zeroes = 13% (8841592832 bytes), duration 218 sec)
So, slow backup, fast restore (fast only with 6.14 kernel both on...
PBS 4.1 - kernel 6.14 - 2x10Gbit LACP, MTU changed from 9000 to 1500.
PVE 9.1.1 - kernel 6.14 - 4x10Gbit LACP, MTU 9000 (i can't change it now)
Still too slow:
INFO: 43% (25.8 GiB of 60.0 GiB) in 26m 53s, read: 15.3 MiB/s, write: 2.4 MiB/s...
Which PVE version are you using ? I have the last no-subscription with downgraded kernel too, but some vm is still very very very very slow... (i am testing only a few and less important vm).
INFO: 67% (40.2 GiB of 60.0 GiB) in 49m 34s, read...
I have downgraded kernel on two clusters and PBS, so they are to the last software available (no subscription) but kernel 6.14.11-4-pve.
One backup was normal, another one is still running, very slow; linux vm with guest agent:
INFO: 32% (19.2...
So, with a 9.1.1 node and 6.14.11-4-pve kernel, I can restore without any problem.
PS: i had not problems with mass live migration, and I use always the same bond of 4x10Gbit with vlans and mtu 9000
On a 9.1.1 node:
uname -a
Linux nodo4-cluster1 6.17.2-2-pve #1 SMP PREEMPT_DYNAMIC PMX 6.17.2-2 (2025-11-26T12:33Z) x86_64 GNU/Linux
I use the same hardware for PBS and PVE (dell R730) and both with bond of 10Gbit ethernet on board (2 or 4)...
I have a slowness problem in restore too, and I can confirm that with a 8.4 host the problem disappear.
Restoring with a 9.1.1 host, after a couple of minutes, i can see only one chunk per minute (or less), and now, for example, I have the...
Same problem here; backups very sloooow and frozen, vm disk corrupted (more windows vms) with PVE 8.4 and PBS 4.1.
So I have upgraded the cluster (6 nodes /ceph) to 9.1.1 and now i will wait, but:
- I am in the middle of an upgrade, so 4 nodes...
