Random Corruption on Filesystem

Gerard's picture


Within the environment, we are running:
Xsan v2.2
A single Promise RAID, 16tbs of storage, in a RAID 6 configuration.
Two Mac Pros acting as MDCs
Qlogic 5600 fiber switch
All fiber & NFS-reshare stations are running 10.6.8
All machines are bound to Open Directory

Randomly, I am seeing QuickTime files, that have been rendered onto the Xsan (whether from Final Cut Pro, After Effects, etc & working properly the previous day, somehow are corrupted the next day.

It is always a QT file, which is unable to play in natively in QT or VLC.

Out of the 16Tbs of storage, we usually hover within the mid 70% before I removed/archive data off the Xsan

Any help would be appreciated.

I remember having v2.2 and having a quicktime corruption files would play fine one day and the next it gave a atom error opening up some movies in quicktime, then apple released xsan filesystem v2.2.1 addressing it http://support.apple.com/kb/HT3927?viewlocale=en_US&locale=en_US

hope that helps, but might need to update xsan to v2.2.1 or even v2.2.2

Just did a check off all my fiber stations and we are running 2.2.1, actually. Going to update to 2.2.2 (possibly this weekend) see how it goes.

We once had a problem where video files would mysteriously corrupt on Xsan.

After a bit of troubleshooting we found that some users were opening these clips in After Effects, which was configured to write out XMP metadata to the video files. Turning off this feature in the After Effects preferences fixed the problem.
