05:05 kraynor5b1 Hey everyone, I'm having some issues with Ganesha/Gluster.  Nobody has been around in the ganesha channel so I thought I would ask here as well as post to the ganesha mailing list.
05:06 kraynor5b1 My Ganesha services keep crashing and I can't figure out why.  I think I might have issues obtaining file locks and that may be related to Gluster but I'm not sure.
05:06 jiffin kraynor5b1: u mean ganesha serverice?
05:07 jiffin not the bricks , rigjt
05:07 kraynor5b1 Right, the gluster volume seems just fine
05:07 jiffin which version of ganesha and gluster are u using?
05:07 kraynor5b1 gluster 3.10
05:07 kraynor5b1 ganesha 2.4.3 now, was trying 2.4.5 before
05:08 jiffin are u using RHEL clients
05:08 jiffin ?
05:08 kraynor5b1 I am using VMware ESXi NFS clients
05:08 kraynor5b1 this worked on 2.3.0
05:08 jiffin okay good to know
05:08 jiffin do u have bt for the core
05:09 kraynor5b1 I just upgraded gluster from 3.7 to 3.10 tonight as well as ganesha from 2.3.0 to 2.4.x
05:09 kraynor5b1 bt?
05:09 jiffin back trace of crash
05:10 jiffin where it got crashed ?
05:10 kraynor5b1 oh, no but I can
05:10 jiffin it will be helpful
05:10 kraynor5b1 yeah, the logs don't tell me much of why ganesha crashes
05:11 jiffin on ganesha 2.4 with windows clients(nfsv3) there some crash related to locking
05:11 jiffin if u have the back trace I can confirm whether it is related or not
05:12 kraynor5b1 but I can't use 2.3.0 with gluster 3.10 right, I would have to roll back to 3.7
05:12 jiffin kraynor5b1: yeah sadly yes
05:12 jiffin and both version are EOLed
05:12 kraynor5b1 hence my attempt hehe
05:12 jiffin lets fix the crash IMO
05:13 jiffin most of the ganesha folks are US time zone, sending mail is also good idea
05:13 kraynor5b1 I have the unfortunate reality of being in a production environment
05:14 kraynor5b1 ugh
05:14 kraynor5b1 question, I have snapshots of my gluster bricks
05:14 kraynor5b1 if I revert back, will that break gluster?
05:16 kraynor5b1 damn, I am on centos 7 minimal so I will need to install bt
05:17 karthik_us joined #gluster
05:20 kraynor5b1 I have to admit I've never done a core dump of a service before
05:23 kraynor5b1 jiffin: if I revert back to the VM snapshot with gl 3.10 and gan 2.3, will the file system not being what it expects screw it all up or will it recover properly?
05:25 psony joined #gluster
05:28 poornima_ joined #gluster
05:29 jiffin kraynor5b1: for coredump easy way attach ur ganesha process to gdb
05:30 jiffin and save the state using gcore or something
05:30 msvbhat joined #gluster
05:30 jiffin or u can use coredump service like abrt or coredumpctl(i prefer this one)
05:31 hgowtham joined #gluster
05:32 jiffin kraynor5b1: sorry I didn;t get ur second question properlyt
05:33 kraynor5b1 oh np, I have a backup of the entire operating system of each node prior to my upgrade
05:33 kraynor5b1 if I revert back (they will consume the same storage again), will gluster behave properly or will I need to recreate the volume?
05:33 prasanth joined #gluster
05:34 jiffin kraynor5b1: so it not just downgrading
05:35 kraynor5b1 right, yeah a full recovery of backup of the operating system with old gluster volume information
05:35 kraynor5b1 the constant would be the brick data
05:36 jiffin I am not the right person answer this question, but IMO it is okay
05:37 jiffin the brick stores volume info as metadata, since volume is not changed old setup can live with same brick data

05:54 kraynor5b1 jiffin:  I rolled back to the old snapshots, for some reason it won't let me enable nfs-ganesha as it says it's already enabled
05:55 kraynor5b1 but when I try to disable it, I get "nfs-ganesha: failed: Staging failed on file03. Error: nfs-ganesha is already disabled.
05:55 kraynor5b1 Staging failed on file02. Error: nfs-ganesha is already disabled.
05:55 kraynor5b1 "

06:06 jiffin kraynor5b1: is your ganesha cluster up and running
06:06 jiffin ?
06:06 kraynor5b1 it is not, I can't get ganesha enabled
06:06 kraynor5b1 due to the above errors
06:06 jiffin u can change that, I just want to know what should be right value
06:06 itisravi joined #gluster
06:06 kraynor5b1 it needs to be disabled
06:07 kraynor5b1 so that I can enable it across all nodes again
06:07 kraynor5b1 node 1 says enabled in gluster v info, but the other two say disabled
06:07 kraynor5b1 :-\
06:09 jiffin do the following
06:10 jiffin edit the value in /var/lib/glusterd/options
06:10 jiffin change "nfs-ganesha=enable" to "nfs-ganesha=disable"
06:10 jiffin restart the glusterd service
06:13 itisravi joined #gluster

06:19 kraynor5b1 jiffin:  one more question
06:19 kraynor5b1 some files are not visible now, but I can see them on the filesystem from the brick
06:19 kraynor5b1 what have I done?  have I lost these files???
06:20 jiffin kraynor5b1: have those files created post upgrade ?
06:20 kraynor5b1 no
06:21 kraynor5b1 I am in the NFS client and do not see them, but I see them on the gluster node in the brick folder
06:21 kraynor5b1 I am a little scared lol
06:21 jiffin kraynor5b1: can u try it from fuse client
06:22 jiffin and please check ganesha-gfapi log while doing a lookup on that file
06:24 kraynor5b1 I can see the files after mounting from linux

06:29 karthik_us joined #gluster
06:29 jiffin kraynor5b1: oh it's bit weird, have u enabled any caching options for gluster volume
06:29 jiffin did get a chance to check gfapi logs
06:31 kraynor5b1 ok, I mounted from the original brick that I was using to host the share and I can see the files now
06:32 kraynor5b1 super weird............
06:32 kraynor5b1 I changed from node 1 to node 3, which is what I was using before when it was working
06:32 kraynor5b1 oh man
06:33 jiffin kraynor5b1: what type of volume are using?
06:33 kraynor5b1 replicated
06:33 jiffin and can u check the files are present in all the replcias
06:34 kraynor5b1 they are yes

17:14 mlow Hi guys, I had a have a newb question.I have two existing consumer NAS's, one with data, one without. I want to run gluster on one of them as a single node, move all data over to it, and then wipe the existing NAS and join it as a replication node. is this possible?
17:15 jstrunk joined #gluster
17:18 kraynor5b Hey guys, I recently restored a backup of all of my nodes to downgrade back to 3.7 from 3.10 following a bug with Ganesha.  I recreated the 3 node replicated volume and it is healing right now, but I feel like there may be a problem.  Would anyone have a minute to look at my logs and point me in the right direction?

19:56 kraynor5b I did not, I'm waiting to see if the heal finishes
19:57 kraynor5b the heal log has a whole lot of scary, so much so I don't even know where to start :)
19:59 JoeJulian All the permitted errors... selinux?
20:01 kraynor5b Disabled
20:03 kraynor5b from that log does it look like it will finish healing?  I've been running heal info constantly and things *are* changing... and the files are fairly large, so perhaps I am overreacting?
