Re: SAN file system mounted as read only

That's a good question. Yes it does also mount "/bckp" for the dataserver to dump the databases. Unfortunately going through the log files I believe nothing was a happening around that time. Also I believe we should have tried to touch a file and confirm it  like how we did it on the "/db" folder.

I opened a case with red hat and this is the response I got

As per the primary analysis on the error message, it seems that there is some issue with storage array. When a scsi layer timeout occurs, the SCSI layer must abort the command so that it cannot complete after we've given up waiting.

Can you please check with your storage team and make sure that there are any hardware issue or error logs available.
