Other OPS?What causes other ops?
I understand that pretty much everything that hits the filer requires something
but I am seeing what looks like a very high number of other ops when I do a
stats show. Does this indicate a problem or is it just a busy box? It’s
a mixed mode volume. Just trying to figure out what’s causing it to work
so hard. Instance
total_ops read_ops write_ops other_ops nfs_read_ops nfs_write_op nfs_other_op
cifs_read_op cifs_write_o cifs_other_o

missing ops? messages file and `qtree stats` data inconsistencySo, I'm comparing the /etc/messages lines that report ops: Fri Oct 2 03:00:00 EDT [XXXXXX: kern.uptime.filer:info]: 3:00am up 38 days, 19:46 4097331567 NFS ops, 121286775552 CIFS ops, 60 HTTP ops, 0 FCP ops, 0 iSCSI ops with the output of qtree stats: Volume Tree NFS ops CIFS ops -------- -------- ------- -------- vol1 qtree1 261704 212370168 Volume Tree NFS ops CIFS ops -------- -------- ------- -------- vol2 qtree2 372425752 37601 vol2 qtree3 26190085 56 I'm collecting the output of `qtree stats` every hour on the hour, to match up with the data output in the messages file. Diff'ing the data on an hourly basis shows that the qtree stats are accounting for about 2/3'rds of the ops on the toaster. Said another way, the data output in the messages file is about 50% higher than the qtree stats. I've checked and double-checked that there is no data, except for /etc, that is not in a qtree. No volumes have been onlined/offlined in the time interval and the filer hasn't been rebooted nor have the qtree stats been zero'ed. So...why the discrepancy? Does qtree stats not count the same ops as the line in the messages file? Until next time...
