ONStor Upgrade

We have found a bug that is tweaked by CIFS against the ONStor virtual file servers. We are going to perform a system upgrade on Wednesday April 8th from 6pm-10pm. Since we have a clustered system there should be no downtime for any of our virtual servers however you could see a performance degradation during the update because all the virtual servers will have to be running on one of the ONStors. The major file systems that are hosted in our ONStor virtual server complex are,

  • /nfshomes
  • /fs/www
  • /fs/ftp
  • lccd NFS shares including /lccdhomes
  • lamp NFS shares
  • glcf NFS shares
  • /usr/local and /opt NFS shares for UNIX clients
