Hi, All: For a given lock space, at the same time, I saved a copy of the output of ?gfs_tool lockdump? as ?gfs_locks? and a copy of dlm_locks. Then I checked the locks presents in the two saved files. I realized that the number of locks in gfs_locks is not the same as the locks presented in dlm_locks. For instance, >From dlm_locks: 9980 NL locks, where --7984 locks are from remote nodes --0 locks are on remote nodes --1996 locks are processed on its own master lock resources 0 CR locks, where --0 locks are from remote nodes --0 locks are on remote nodes --0 locks are processed on its own master lock resources 0 CW locks, where --0 locks are from remote nodes --0 locks are on remote nodes --0 locks are processed on its own master lock resources 1173 PR locks, where --684 locks are from remote nodes --32 locks are on remote nodes --457 locks are processed on its own master lock resources 0 PW locks, where --0 locks are from remote nodes --0 locks are on remote nodes --0 locks are processed on its own master lock resources 47 EX locks, where --46 locks are from remote nodes --0 locks are on remote nodes --1 locks are processed on its own master lock resources In summary, 11200 locks in total, where -- 8714 locks are from remote nodes (entries with ? Remote: ?) -- 32 locks are on remote nodes (entries with ? Master: ?) -- 2454 locks are processed on its own master lock resources (entries with only lock ID and lock mode) These locks are all in the granted queue. There is nothing under the conversion and waiting queues. ====================================== >From gfs_locks, there are 2932 locks in total, ( grep ?^Glock ? and count the entries). Then for each Glock I got the second number which is the ID of a lock resource, and searched the ID in dlm_locks. I then split the searched results into two groups as shown below: --46 locks are associated with local copies of master lock resources on remote nodes --2886 locks are associated with master lock resources on the node itself ====================================== Now, I tried to find the relationship between the five numbers from two sources but ended up nowhere. Dlm_locks: -- 8714 locks are from remote nodes -- 32 locks are on remote nodes -- 2454 locks are processed on its own master lock resources Gfs_locks: --46 locks are associated with local copies of master lock resources on remote nodes --2886 locks are associated with master lock resources on the node itself Can anyone kindly point out the relationships between the number of locks presented in dlm_locks and gfs_locks? Thanks for your time on reading this long question and look forward to your help. Jas -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
