04:29 fareeed hey, I'd like to use gluster for a project but I'm not sure if it's compatible with the other components
04:30 fareeed I already have a really big tub of vasoline
04:30 fareeed and a willing partner
04:30 fareeed but I'm not sure if the ball gag is necessary

11:11 samppah arash: could you please tell more what you want to do?

11:14 samppah yeah, that's possible
11:15 samppah you can either use thos disks to create raid group or let gluster manage all of them
11:15 arash do u have any documents can help me
11:15 arash this is for test with
11:16 arash 2 servers our final goal is replace ceph with glusterfs
11:16 arash i mean about clustering more than 250 servers
11:17 samppah @doc

14:16 T3 JoeJulian, while working on network investigation for my servers, I noticed something that is not related to network. If I try a # df -Th, it may hung like 10+ minutes to give the output on servers where gluster volumes lives
14:16 T3 the mount points are like these:
14:17 T3 /dev/mapper/data_vg-data_lv     ext4           1007G  495G  462G  52% /export/images1-1
14:17 T3 images1.mydomain.com:/site-images fuse.glusterfs 1007G  495G  462G  52% /var/www/site-images
14:17 T3 client and server on the same local server
14:18 T3 CPU load is ok: load average: 0.07, 0.17, 0.19
14:18 T3 memory is being consumed:
14:18 T3 total       used       free     shared    buffers     cached
14:18 T3 Mem:          7.8G       7.4G       369M       2.0M       4.3G       1.5G

14:21 T3 Swap:         508M         0B       508M
14:21 T3 after that, I still get hanging # df -Th
14:26 T3 JoeJulian, the same issue happens when I try using tab to browse directories inside a mounted gluster client, locally
14:26 T3 the tab hangs

16:26 davidbitton having a hard time Googling for this. i rebooted the first server in my replicated volume pair, and my clients stopped being able to real files. i checked, and my client can connect to port 24007 via telnet on both peers. i see the failure to connect in the client log file.
16:27 davidbitton what are the troubleshooting steps for this?
16:27 davidbitton thanks!

17:15 samppah davidbitton: what version you are using? do you have quorum configured?
17:15 davidbitton the servers are at 3.5.1
17:16 davidbitton clients are 3.6.1
17:16 davidbitton i discovered this when i took down a server in order to upgrade it
17:18 samppah can you sent output of "gluster volume info" command to pastie.org?
17:20 samppah http://www.gluster.org/community/documentation/index.php/Upgrade_to_3.6 hmm, this recommends updating servers first, not sure if that's mandatory
