Hi JAB - I think I've figured out what syncSambaMetadataOps does - I
think it's a performance optimsation for the vfs_syncops module. With
syncSambaMetadataOps set, you can then set:
syncops:onmeta = no
I found this in:
http://sambaxp.org/fileadmin/user_upload/SambaXP2011-DATA/day2track1/SambaXP%202011%20Ambach%20Dietz.pdf
under "metadata synchronization performance" (slides 21 & 22) referred
to as the mysterious "new (internal) GPFS parameter"
Of course, since it's undocumented this is purely guesswork on my part -
would be good to get confirmation from IBM on this.
Also - I'd love to get the output of "testparm -v" and "mmfsadm dump
config" from an IBM SONAS cluster node to see what the best practise
GPFS + samba settings are. Any chance of that from an IBMer?
Cheers,
Orlando
