NAS DRIVE :: Showing READ-ONLY Error after few days

[phoneme]

We are using the common storage pool which is attached as the Network storage and then we are making the Volumes and allocating to the Virtual Machines .
The Common Storage Volume named Hartron-EDU is attached to the PVE Node as storage pool . as shown in image named " Hartron-EDU-Disk-Common-Storage.png "

This pool is then mounted on the

Now this storage is further used as a disk in VM named Hartron 221 as shown in Hartron-EDU-Disk-Common-Storage.png





Now once it is mounted as a volume in the disk in VM then after running for few days it is giving the error . 221-VM-Snapshot.png



I would request you to suggest if it is the right way of using the NAS based storage drive ?
How to remove the error in the same ?

[dcsapak]

how is that volume mounted? a 'mount' and 'df' should show more info.

also check your logs and dmesg why its getting mounted readonly
