Re: Issue with duplicated files in gluster 3.10

Hello Ravishankar,
we had to change the directory as we fixed that one, so please check these links which refers to a new (broken) path:

https://nopaste.me/view/1ee13a63 LS debug log
https://nopaste.me/view/80ac1e13 getfattr
https://nopaste.me/view/eafb0b44 volume status

Thanks in advance.

Hi,
I'm Andrea's collegue. I'd like to add that we have no trusted.afr xattr on the root folder
Just to confirm, this would be 'includes2013' right?

where those files are located and every file seems to be clean on each brick.
You can find another example file's xattr here: https://nopaste.me/view/3c2014ac
This behavior causes the directory which contains those files undeletable (we had to clear them up on brick level, clearing all the hardlinks too).
This issue is visible on fuse mounted volumes while it's not noticeable when mounted in NFS through ganesha.

Could you provide the complete output of `gluster volume info`? I want to find out which bricks constitute a replica pair.

Also could you change the diagnostics.client-log-level to DEBUG temporarily, do an `ls <directory where you see duplicate entries>` on the fuse mount  and share the corresponding mount log?
Thanks,
Ravi

Thanks a lot.

Hi community,

we ran an extensive issue on our installation of gluster 3.10, which we did upgraded from 3.8.8 (it's a distribute+replicate, 5 nodes, 3 bricks in replica 2+1 quorum); recently we noticed a frequent issue where files get duplicated on the some of the directories; this is visible on the fuse mount points (RW), but not on the NFS/Ganesha (RO) mount points.


A sample of an ll output:


---------T 1 48 web_rw     0 Mar 10 11:57 paginazione.shtml
-rw-rw-r-- 1 48 web_rw   272 Feb 18 22:00 paginazione.shtml

As you can see, the file is listed twice, but only one of the two is good (the name is identical, we verified that no spurious/hidden characters are present in the name); the issue maybe is related on how we uploaded the files on the file system, via incremental rsync on the fuse mount.

Do anyone have suggestion on how it can happen, how to solve existing duplication or how to prevent to happen anymore.

Thanks in advance.
Best regards,
andrea
