有個guest在備分時偶爾會出現以下的錯誤 怪的狀況不是每天 而是不定時會發生 109: 2021-11-01 23:34:40 INFO: Starting Backup of VM 109 (qemu) 109: 2021-11-01 23:34:40 INFO: status = running 109: 2021-11-01 23:34:40 INFO: VM Name: 0.226-examtest 109: 2021-11-01 23:34:40 INFO: include disk 'virtio0' 'nfs218_system:109/vm-109-disk-0.qcow2' 100G 109: 2021-11-01 23:34:40 INFO: backup mode: snapshot 109: 2021-11-01 23:34:40 INFO: ionice priority: 7 109: 2021-11-01 23:34:40 INFO: creating Proxmox Backup Server archive 'vm/109/2021-11-01T15:34:40Z' 109: 2021-11-01 23:34:41 INFO: started backup task '2ba8928b-bd3b-4e90-a62f-7fd1a37d51d8' 109: 2021-11-01 23:34:41 INFO: resuming VM again 109: 2021-11-01 23:34:44 ERROR: VM 109 qmp command 'cont' failed - got timeout 109: 2021-11-01 23:34:44 INFO: aborting backup job 109: 2021-11-01 23:34:44 INFO: resuming VM again 109: 2021-11-01 23:34:44 ERROR: Backup of VM 109 failed - VM 109 qmp command 'cont' failed - got timeout
查了一下forum有人碰到相同的情況
是建議修改
/usr/share/perl5/PVE/QMPClient.pm
in line 134
} else {
$timeout = 3; # default
to
} else {
$timeout = 8; # default
我直接把 $timeout改為30
restarted the pve daemons
for service in pvedaemon.service pveproxy.service pvestatd.service ;do
echo "systemctl restart $service"
systemctl restart $service
done
目前就先醬改了
再觀察看看
2021/10/31
proxmox更新到7版後
在管理介面 mount nfs 可以選 v3 或 v4
用fio測一下 v3 和 v4 的效能差別
config 如下
# This job file tries to mimic the Intel IOMeter File Server Access Pattern

測三次 取最後一次的值如下

初步看起來 v4 稍微好一些
2021/10/21
升到 promox 7 後
有几台guest都出現了以下的問題
可是使用 badblocks xfs_repair 進行檢查
都沒有發現任何錯誤
而且看了一下nas各個HD的資訊
也沒有發現任何狀況
還在找原因
之前有一台是發生在swap 區
目前把swap 關掉
然後把 ram 從2G調到 4G
觀察到現在沒有異常
不知道是不是ram 的問題
2021/10/24 更新
發生狀況的有四台几器 共同的情況是這些guest的io都很大
分別處理如下
ntopng因為升版後 system id 變了 所以移至 LXC 後 重新要了新key
librenms 下載了新版的vm 把資料移轉到新几器上
https://docs.librenms.org/Support/FAQ/#how-do-i-move-my-librenms-install-to-another-server
剩下cacti 跟 syslog
從log來看是 write 時候的問題
目前所有的guest hd 預設都是使用 no cache
想說會不會是效能的問題
https://adminkk.blogspot.com/2016/05/wsus-proxmox-winmount-nfs-wsus-iscsi.html
於是把上面二台
一台調成 write back
一台調成 write through
到目前跑了二天
持續觀察中
