osd commands
statistic
Get rpc statistics of a server
You can also use the ID of osd list, e.g.: #osd stat 2
That gives the same output.
# osd statistic zyklop20-al funny kvno (256) in ticket, proceeding Since 2009-11-15 04:00:04 (458674 seconds == 5 days, 7:24:34 hours) Total number of bytes received 96448669084672 87 tb Total number of bytes sent 95887024458752 87 tb rpc 220 Dummy 17884 rpc 131 read 4 rpc 170 list 3 rpc 314 updatecounters 93420271 rpc 211 CopyOnWrite 1972564 rpc 110 create 1 rpc 121 write 140 rpc 187 examine 25 rpc 185 examine0 1 rpc 150 incdec 1 rpc 311 Variable 2 rpc 312 statistic 2

# osd listosds id name size state usage rpri wpri own loc flag lun sizerange 1 local_disk 0 gb up 0.0 % 100 64 --- --- --- 0 (0kb-1mb) 2 zyklop20-al 10694 gb up 2.5 % 64 64 --- --- --- 37 (1mb-2tb) 4 arch 46 gb up 0.3 % 64 64 --- --- arch 0 (0kb-10gb)
Important: You can use the i instead of the Name.
osd
show single osddb entry
You can also show only the entry of a given OSD:
e.g. #osd osd 2
# osd osd

highWaterMark = 800 per mille used
minWipeSize = 0 MB
chosen = 0 (should be zero)
volumes
list volumes
# osd volumes zyklop20-al osddb: Could not get afs tokens, running unauthenticated. RX xdr error Cannot list volumes, error = 13 Request aborted.
servers
show server osddb entry
# osd servers
addserver
create server entry in osddb
# osd addserver -id <ip address> -name <osd name>
deleteserver
delete a server entry
# osd deleteserver -id <server name or ip-address>
policies
show policy osddb entry
# osd policies
addpolicy
add a policy
# osd addpolicy -id <policy number> -name <short name for policy> -policy <string representation as given by policies -cryptic>
You can choose the id by yourself, but watch out if the id already exists!
