Re: Fwd: iSCSI Lun issue after MON Out Of Memory

I assume you mean you only had 1 mon and it crashed, so effectively the iSCSI suddenly went offline?

I suspect somehow that you have corrupted the NTFS volume, are there any errors in the event log?

You may be able to use some disk recovery tools to try and fix the FS. Maybe also try mounting the RBD on a linux host and using the Linux NTFS tools to try and mount the volume?

Hello friends,

I had RBD images mapped to Windows client through iSCSI, however, the
MON got OOM due to some unknown reason. After rebooting MON, I am able
to mount one of the image/ iSCSI LUN back to client, second image when
mapped is shown as unallocated on windows client. I have data on that
image,hence cannot reformat the LUN.

Please suggest.

I am able to see objects when I do rados ls for that pool with image id.

Thanks,

Daleep Singh Bais
