[Lustre-discuss] Persistent write-back cache

[Lukas Hejtmanek]

Hello,

I noticed that manual refers to write-back cache feature:
4.4.9 Configure a Client with a Persistent Write-Back Cache

On the client format a loop device cache for OSS and MDS cache combined with
mkfs.lustre:

mkfs.lustre --loop --ost --mdt --cachefor=<mds hostdesc>[,<mds2 hostdesc>
..]:/<fsname> <cache file>

Now simply mount the cache:

mount.lustre -o loop <cache file> <cli mtpt>


http://manual.lustre.org/manual/LustreManual16_HTML/ConfiguringLustre.html

unfortunately, mkfs.lustre does not support the --cachefor option. Is this
option deprecated or something in roadmap?
