I have a PVE, the version is 8.4.19, and two Synology NAS as backup storage (nas061 / nas66)
The previous backup plan had been working well
But about two or three weeks ago, I started to receive backup failure notification emails, which probably said storage not online.
Because this machine is not very important, I didn’t deal with it specially.
I have more free time recently, so I thought I would solve this problem.
But I found some very strange problems
I removed the NAS nas66 and rejoined it.
When I selected export, it took a long time to scan before nfs export appeared.
But after selecting it and pressing Add, the error "create storage failed: storage 'nas66' is not online (500)" still appears.
PVE host information
```
[root@pve22 ~]$ cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 12 (bookworm)"
NAME="Debian GNU/Linux"
VERSION_ID="12"
VERSION="12(bookworm)"
VERSION_CODENAME=bookworm
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"
[root@pve22 ~]$ uname -r
6.8.12-2-pve
```
Both Synology NAS use NFS V3, and the settings on the NAS have not been changed.Any suggestions on how to deal with this problem?
