Deduplication - PDVFS errors
Hi All, I'm struggling with an issue that has occured with deduplication storage (or thats what it appears to be to me) on one of our managed media servers. All of a sudden most of the jobs that are run on this server are not completing. They start and go into the "Active: Running - Backup" state, but the average job rate for 75% of the jobs is only 1-2 MB/min or just stops at 0 MB/min. I have checked the event logs today and can see that PDVFS errors have appeared as well. Here is what we are getting (oldest first): Log Name: Application Source: PDVFS Date: 15/08/2016 22:00:53 Event ID: 50000 Task Category: None Level: Error Keywords: Classic User: N/A Computer: RESBE03.RES.TSS.NHS.UK Description: An error occurred in the PDVFS driver: <ERR> PdvfsOpen: O_CREAT not set Log Name: Application Source: PDVFS Date: 15/08/2016 22:00:53 Event ID: 50000 Task Category: None Level: Error Keywords: Classic User: N/A Computer: RESBE03.RES.TSS.NHS.UK Description: An error occurred in the PDVFS driver: <ERR> PdvfsOpen: failed for "/RESBE03/2/BEData/_BE101_.TMP": No such file or directory (2) Log Name: Application Source: PDVFS Date: 15/08/2016 22:12:23 Event ID: 50000 Task Category: None Level: Error Keywords: Classic User: N/A Computer: RESBE03.RES.TSS.NHS.UK Description: An error occurred in the PDVFS driver: <ERR> PdvfsPread: pdvfs_io_pread_fake failed: No such file or directory (2) Log Name: Application Source: PDVFS Date: 15/08/2016 22:39:17 Event ID: 50000 Task Category: None Level: Error Keywords: Classic User: N/A Computer: RESBE03.RES.TSS.NHS.UK Description: An error occurred in the PDVFS driver: <ERR> PdvfsPread: fd->dep or fp->dep->stat NULL I have tried accessing the pdvfs file path and it is present, I have been able to navigate (very slowly) to the directory mentioned in the alerts, \\.pdvfs\RESBE03\2\BEdata, I'm still waiting for it to open to see if the mentioned files are present as well. While I'm confident this is pointing to a storage error, I',m confused as to he extent of the issue as we are still seing jobs completing without any issues?? The server itself is running Backup exec 2015 FP4, Windows 2012 R2. Dedupe storage is a VNX5500. Thanks in advance for any insight anyone can provide on this. P.S. Other media servers we are running are not affected by this issue.
