[Lustre-discuss] OST went down running Lustre 1.6.6

[Brian Stone]

Yes, I was using corruption to mean incomplete files. So, let me 
rephrase, is there a way to avoid "incomplete files" after an OSS crash, 
reboot, etc.? The lustre devices were not deactivated from the clients 
and MDS, would that possibly avoid the purge of data?

Thanks,
Brian Stone
