08:14 xavih atinmu: hi
08:21 pranithk xavih: It is lunch break here :-)
08:21 xavih pranithk: no problem :)
08:21 pranithk xavih: I am looking at the inodelk crash on clearlk mail you sent. Could you tell me the steps to re-create the problem. Or a bug that describes the problem?
08:23 xavih pranithk: I think the problem happens when the getxattr fop that requests the clear-locks uses a lock itself
08:23 xavih pranithk: in this case, there will be a lock that clear-locks will 'unlock'
08:23 xavih pranithk: the clear-locks function does not remove this lock from the locks held by a client
08:24 xavih pranithk: this means that when the connection used to clear the locks is terminated and all locks held by that client are removed, it will find an already destroyed lock in the client list
08:25 xavih pranithk: basically, to solve this, it will need to remove the lock from the client list when clearing a lock
08:25 xavih pranithk: however doing this should require to acquire the client lock
08:26 xavih pranithk: I've been thinking on implementing clear-locks in another way, iterating each client, and for each client each lock
08:26 pranithk xavih: locks code is very difficult to understand. I thought a core would be helpful in understanding.... Once I understand the problem, I will be in a better position to answer the questions
08:27 xavih pranithk: I can generate one later
08:27 xavih pranithk: I'll also open a bug to add more information
08:27 pranithk xavih: But you said you found it as part of some bug somebody raised?
08:27 pranithk xavih: That should be good enough for me to start finding out what is happening.
08:28 xavih pranithk: yes, in ec I was acquiring an inodelk for all getxattr calls. This is not necessary for clear-locks request, but doing so caused the other bug
08:28 xavih I solved this by not locking this special getxattr, but the other problem remains
08:28 atinmu xavih, hi, I have a meeting now for 1 hour, will catch u after that, is it ok with you?
08:28 xavih pranithk: no problem
08:29 xavih pranithk: for later... this is the original bug: https://bugzilla.redhat.co​m/show_bug.cgi?id=1181977
08:29 glusterbot Bug 1181977: high, unspecified, ---, xhernandez, POST , gluster vol clear-locks vol-name path kind all inode return IO error in a disperse volume
08:30 pranithk xavih: Thanks for this xavi. I will respond it once I figure out what is happening. We have a meeting for 90 minutes now. Will resume looking into this after that
