Disk in Read-Only mode after maintenance

Dear Customers,

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.

  • Reboot Time and Date
    US Pacific Standard Time: Wednesday Feb. 11th, 2015 between 15:00 PM and 15:30 PM.
    Japan Standard Time: Thursday Feb. 12th, 2015 between 08:00 AM and 08:30 AM.
  • Nature of Failure
    Storage system upgrade work made the servers' disks unavailable for about 5 minutes.
  • Affected Location
    Certain customer servers located in USA cloud (us001).
  • Services Affected
    The disks will have failed into read-only mode.  This is an automatic file system response to such errors.

Please don't hesitate to contact us if you require any further information.
Sincerely,
GMO CLOUD Support
