cifs_other_ops includes metadata operations. If you’re searching for files in a directory tree, or looking up file permissions, or looking up file ownership – these are all metadata operations.
Not uncommon at all to see.

I’m looking at the Performance Manager graph for a volume that is a CIFS share. It graph has 4 stats: cifs_read_ops, cifs_write_ops, cifs_other_ops, cifs_ops.
CIfs_reads_ops and Cifs_write_ops are VERY few totaling only 0-30/sec, but mostly at 0. Cifs_other_ops is a constant 130/s to 180/s, but NEVER dropping below a floor of 130/s. Cifs_ops is similar to Cifs_other_ops, but somewhat higher.
The help metrics don’t exactly help explain these.
Q) What is cifs_other_ops and cifs_ops?
Q) What would a CIFS client be doing to cause few reads/writes, but lots of cifs_other_ops and cifs_ops?
For example, at one point I have these values: cifs_read_ops 3 cifs_write_ops 28 cifs_other_ops 135 cifs_ops 160
Thanks
Rick
