Hi, Also I forgot to mention there are DUMP and PORTBYBRICK calls too. I understood these too calls are to get updated on gluster configuration. But all these two calls are to a particular node only while there are total (2+1)*3= 6 nodes in my configuration. Why so? What exactly is DUMP and PORTBYBRICK? Regards Jeevan.

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?

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

Hi Ben, Yes, I was referring to the same link before and I think most of the FOPS I've understood from the definitions there and I'll update if I found any corrections or new definitions. Btw, my previous underatanding about LOOKUP is wrong, its NOT dns lookup. Regards, Jeevan. On Nov 14, 2017 11:02 AM, "Ben Turner" <bturner at redhat.com> wrote: Here is some of the

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

trusted.io-stats-dump is a virtual (not physical) extended attribute. The code is written in a way that a request to set trusted.io-stats-dump gets 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. HTH, Krutika On

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, 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]

Hi, >From strace, I can see the system calls setxattr and getxattr. Two things I don't understand is: 1. how 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, 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, 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,

It''s been nearly a year since the patches needed to implement a reflinked copy between subvolumes have been posted (http://permalink.gmane.org/gmane.comp.file-systems.btrfs/9865 ) and I still get "Invalid cross-device link" error with Linux 3.2.4 while I try to do a cp --reflink between subvolumes. This is a *very* useful feature to have (think offline file-level
