Hi there, We have 27TB on three OSSes. Each has two OSTs. Now one of the OSS servers has died, and it may take weeks until it is repaired. Can I just plug the RAID with the OSts belonging to the dead OSS into one of the other OSSes? If so, how do I do this without data loss? The Lustre version is 1.6.7.

The Lustre version is 1.6.7.You should be able to, but you will need to use --writeconf. This is documented in the Lustre manual (it is the same as changing the IP address of an OSS).
