There is already ZFS compression for metadata enabled at all times, but with DoM we will also store data on the MDT.</p> <p>Since the MDT will typically also be located on flash storage, from a cost and performance perspective it makes sense to compress the data that is stored there.</p> LU-11137

Enable ZFS compression on MDT by default

Bug Minor Resolved Incomplete Mikhail Pershin Andreas Dilger DoM2 Tue, 10 Jul 2018 17:53:01 +0000 Sun, 16 Jan 2022 09:07:23 +0000 Sun, 16 Jan 2022 09:07:23 +0000 Lustre 2.12.0 0 3 <p>It would be good to verify that this does not affect performance on the MDT significantly.</p> <p>Andreas, is this still worth to implement or outdated?</p> <p>This is probably something that should be decided by the admin. Unlike ldiskfs, it is possible to change ZFS configuration after installation, so enabling compression can be done at any time. </p> Development Rank 1|hzzyzr: Rank (Obsolete) 9223372036854775807 Severity
