Lustre Server OS Version: CentOS 7.4 Lustre Server version: 2.10.2 Server Kernel version: 3.10.0-693.5.2 Filesystem: ldiskfs
I have an older disk array with a hardware failure. I suspect the drives and data are still valid. What I plan to do is migrate the data off of a similar model array, move the drives and migrate the data from the failed array. In order to do this, I need to migrate just an OST to a different device. I can't use lfs_migrate, because that works at the file level. I suspect the best route to go is to create a new device and use "dd" to copy the contents of the source device to the target device. Is there a better solution? Anything I should be aware of regarding dd and an OST? The arrays in question are enterprise class systems with caching controllers configured for RAID6.
