Re: [Moosefs-users] mfsmetarestore performance question

[Allen, B. S <bs...@la...>]

With a 2,408,276 object MFS (31T used out of 106T), it took me 30 seconds or there about to run mfsmetarestore. If you have a backup of your /var/mfs (data directory) or metalogger copies, I'd suggesting trying to run mfsmetarestore on that data on a separate system.

Examples:

mfsmetarestore -m metadata_ml.mfs.back -o metadata_restore.mfs changelog_ml.0.mfs changelog_ml.1.mfs
mfsmetarestore -m metadata.mfs.back -o metadata_restore.mfs changelog.0.mfs

The MFs installation had several million files (chunks) occupying about 4.8 TB of space. That mfsmetarestore has been running for about 18 hours now and is still not done. Is that normal? How long should I expect it to run?
