Raid-Z2 Used Space 100%, after it lost connection via iSCSI.

[Kodya]

Hi there.
I create zpool in Z2 with mirroring.
i'm created zvol and configure it for iSCSI using.
I forget about disk space, and someday my zvol become Used Space 100%.... and my host's lost connection to iscsi zvol....
Because i'm using oracle vm the filesystem of zvol = ocfs2.. and if i try mount this filesystem, i get next error.

dmesg | tail

Please describe your pool and hardware in detail, as per the Forum Rules.

Use a VM that can read that filesystem and mount the zvol to it as a device.

A TrueNAS host won't be able to mount that filesystem.
