Hi, There's no client activity and I have collected tcpdump for 5 mins on one of the glusterFs sever which is also a client with gluster NFS mount. From tcpdump I see that for every few seconds, STAT & STATFS commands are run. For whichctory are these commands being run and why? Regards, Jeevan. -------------- next part -------------- An HTML attachment was scrubbed... URL:

An ESTALE error usually means the gfid could not be found. Does repeating the "rm -rf" delete the directory?

Hi, I am trying to understand how the extended attribute trusted.io-stats-dump works. setfattr -n trusted.io-stats-dump -v /tmp/gluster_perf_stats/io-stats-pre.txt /mnt/gluster/gv0_glusterfs I can see that the io-stats-pre.txt is created. But how and what happened in the background? And why I can't I see the attribute with getfattr again? getfattr -dm- /mnt/gluster/gv0_glusterfs # file:

Hi, Can I get a brief description of all the FOPS in gluster or the location of the source code file so that I will try to get an understanding myself? Few FOPS I'm not clear like FORGET, UNLINK, FLUSH, LOOKUP Or is there a way I can tunnel through the FOPS that that are happening in the background for each operation? I have tried this to find from a brick logfile in TRACE mode, but there

Hi all, I haven't found any root cause or workaround for this yet. Can any one help me in underatanding the issue? Regards, Jeevan.

Hi, After running rm -rf on a directory, the files under it got deleted, but the directory was not deleted and was showing stale file handle error. After 18 minutes, I'm able to delete the directory. So could anyone help me in knowing what could have happened or when in general I get such errors. The following is NFS log: [2017-12-21 13:56:01.592256] I [MSGID: 108019]

...bypassed at the io-stats translator layer on the stack and there it gets converted into the action of dumping the statistics into the provided output file path. See io_stats_setxattr() implementation in io-stats.c for more details.

...does the file got created so quickly, from where it read the stats. 2.why is the added attribute missing if I check with getfattr? Regards, Jeevan.

Hi, I don't think it happens as then later it would not be possible to get the file location by hashing. Am I right?

Hi, I'm trying to get in over my head with the different glusterFs volume types and their affect on performance. But few things In not clear By analyzing tcpdump, I can see that the reads happen from only one host/brick out of the replicated set. Then what makes replicated type gives better read performance than any other volume type except striped types. Regards, Jeevan. --------------

Hi, We have around 60 hosts and each of them acts as glusterFs clients as well as server. To achieve HA, my underatanding is that we can use Ganesha NFS alone (and not Kernel NFS) and for above 3.10 versions, the HA packages are not ready yet. So, I'm thinking if I can avoid HA by making each client acts as server for itself. i.e.,the server name specified while mounting is localhost. So,

Hi, What I meant was that every host acts as nfs server for itself alone. A is mounted on A, B is mounted on B etc. So, if a host is crashed or storage of the host is not available, other hosts won't be affected. And how bad can be the performance overhead in having multiple nfs servers? Regards, Jeevan. On Nov 15, 2017 10:07 AM, "Soumya Koduri" <skoduri at redhat.com>

Hi, I'm trying to find documentation for HA setup on Ganesha nfs in 3.12 version. But the documentation contains glusterfs-ganesha instructions, instead of storhaug. I'm new to the ha cluster setup and I am confused. Any information on it is very helpful. Thanks! Regards, Jeevan. -------------- next part -------------- An HTML attachment was scrubbed... URL:
