+++ This bug was initially created as a clone of Bug #1001040 +++ Description of problem: Error detected while setting tuned profile to a volume name which has hyphen in it. Version-Release number of selected component (if applicable): RHS-2.1-20130820.n.0 How reproducible: Always Steps to Reproduce: 1. Install RHS 2.1 2. Create volume with hyphen in it. "glance-volume, in this case" 3. Set tuned profile. Actual results: [root@localhost ~]# tuned-adm profile rhs-virtualization Reverting to saved sysctl settings: [ OK ] Calling '/etc/ktune.d/tunedadm.sh stop': setting readahead to 128 on brick devices: ERROR: could not find mountpoint for brick directory /rhs/bricks/cinder ERROR: could not find mountpoint for brick directory /rhs/bricks/glance [ OK ] Reverting to cfq elevator: dm-0 dm-1 dm-2 dm-3 [ OK ] Stopping tuned: [ OK ] Switching to profile 'rhs-virtualization' Applying ktune sysctl settings: /etc/ktune.d/tunedadm.conf: [ OK ] Calling '/etc/ktune.d/tunedadm.sh start': setting readahead to 4096 on brick devices: ERROR: could not find mountpoint for brick directory /rhs/bricks/cinder ERROR: could not find mountpoint for brick directory /rhs/bricks/glance [ OK ] Applying sysctl settings from /etc/sysctl.conf Applying deadline elevator: dm-0 dm-1 dm-2 dm-3 [ OK ] Starting tuned: [ OK ] [root@localhost ~]# Expected results: Tuned profile should be set correctly. ERROR's should not be detected. Additional info: This happens because of "ls | grep $ipaddr | awk -F: '{ print $2 }' | sed 's/\-/\//g'" which replaces "-" to "/" --- Additional comment from Gowrishankar Rajaiyan on 2013-08-26 07:45:16 EDT --- (In reply to Gowrishankar Rajaiyan from comment #0) > Description of problem: Error detected while setting tuned profile to a > volume name which has hyphen in it. > Correction: Error detected while setting tuned profile if the brick directory has "hyphen" in it. glance-volume and cinder-volume in this case. --- Additional comment from Ben England on 2013-08-27 13:28:53 EDT --- Is there any way to work around the problem by not using a hyphen in the brick directory name? How about using an underscore or a dot? To understand this problem, see the set_brick_ra() subroutine within /etc/tune-profiles/rhs-virtualization/ktune.sh: ls | grep `hostname -s` | awk -F: '{ print $2 }' | sed 's/\-/\//g' >> $bricklist The entries in this directory /var/lib/glusterd/vols/your-volume/bricks/ look like this: gprfs045-10ge:-mnt-brick0-brick gprfs047-10ge:-mnt-brick0-brick gprfs046-10ge:-mnt-brick0-brick gprfs048-10ge:-mnt-brick0-brick So the grep command selects the local host's bricks, the awk command filters out the hostname. The directory path for the brick is encoded by Gluster replacing "/" with "-". This is a poor choice because a filename can have a "-" in it, so this much is a Gluster bug. The script is trying to convert back to a path specification for the brick directory with the sed command, but this doesn't work because the brick directory's filename has a "-" character in it. My only other option AFAIK is to parse the /var/lib/glusterd/vols/$volume/${volume}-fuse.vol file. If you need this fixed now and the workaround won't do, you have to let me know ASAP. --- Additional comment from Gowrishankar Rajaiyan on 2013-08-27 16:14:33 EDT --- I don't see a work around to the problem here. Using an underscore or a dot or no special characters is a way to evade the issue and would have to be documented as a known issue or am I missing the work around ? --- Additional comment from Bala.FA on 2013-08-27 20:40:14 EDT --- This fix is available at https://code.engineering.redhat.com/gerrit/12059. Ben, could you help on reviewing this patch?
Patch is at https://code.engineering.redhat.com/gerrit/#/c/12070/
Can we please get tuned profiles from Big Bend into RHS 2.0 U6?
As this bug is clone of Bug#1001040 addressed in RHS 2.1 and it wasn't addressed/required in RHS 2.0 Update 6. So closing it now.
