During the storage maintenance performed February 11th from 09:00 AM to 02:30 AM Wednesday (PST), a few virtual servers and load balancers failed into read-only mode. We have already contacted those customers who were affected.
All affected servers have been restarted. This will fix the disk's read-only mode. Although, this will also trigger a FSCK check of the disk during boot. Depending on the server's settings further action may be required. The FSCK may be waiting for confirmation to continue and/or to correct errors.
The status of the disk can be determined by the mount command.
