4. Service Reports
PDU was installed between the UPS and the cluster, after that, valtical00 can’t start up due to connection problem with a hard disk which serves as /data5
This disk was removed and checked but no bad block was found, then it was reconnected to valtical00 via USB line, a new 2T hard disk was delivered and used to replace the previous /data5, data are transferred to this new hard disk but some problem happened during NFS mouting, fixed later.
Unexpected power cut in the cluster room last Friday morning, recovered later
