[Gluster-users] __Geo-replication status is getting Faulty after few seconds

[Aravinda]

If the backend GFID file only exists in Master 1, then it looks like stale GFID exists due to some failure. Run getfattr on that file to see if it shows any file path in gfid2path xattr. Please share the output of the following command.



getfattr -d -m . ./d5/3f/d53fad8f-84e9-4b24-9eb0-ccbcbdc4baa8



Meanwhile move this file to a backup location and see if Geo-rep succeeds.



We can introspect the details about the GFID d53fad8f-84e9-4b24-9eb0-ccbcbdc4baa8. Please share the matching changelog files from 



grep -R "d53fad8f-84e9-4b24-9eb0-ccbcbdc4baa8" .glusterfs/changelogs/*

Hi mailto:hunter86_bg at yahoo.com,



As mentioned earlier this gfid has "1" in 2nd column of 'ls' command output, which means
 this gfid doesn't have any other hardlink.



[root at master1 .glusterfs]# ls -l ./d5/3f/d53fad8f-84e9-4b24-9eb0-ccbcbdc4baa8
 -rw-r--r-- 1 root root 174592 Jan 22 15:06 ./d5/3f/d53fad8f-84e9-4b24-9eb0-ccbcbdc4baa8


Still, I have searched in "/opt/tier1data2019/brick/.glusterfs" and there is only one file comes with samefile
 option, which is gfid itself, please check the following output.



[root at master1 .glusterfs]# find . -samefile ./d5/3f/d53fad8f-84e9-4b24-9eb0-ccbcbdc4baa8
 ./d5/3f/d53fad8f-84e9-4b24-9eb0-ccbcbdc4baa8




You have mentioned the other option to link it somewhere on the real filesystem and then sync it to the other
 brick. Here, what do you mean by the real filesystem? Do you want me to link this GFID with an existing file on the brick? Or do you want the GFID to be linked with some temporary file, say, on "/tmp/test_file," and then sync "/tmp/test_file" and "/opt/tier1data2019/brick/.glusterfs/d5/3f/d53fad8f-84e9-4b24-9eb0-ccbcbdc4baa8"
 to master2 and master3 nodes?



Many thanks,

Anant

EXTERNAL: Do not click links or open attachments if you do not recognize the sender.

The other option around (if indeed is the only in .glusterfs) is to have it link somewhere on the real filesystem structure and then sync it to the other bricks.

If georep works again - just remove it from the fuse and check if it will get deleted or not.

It's a hard link, so use find's '-samefile' option to see if it's the last one or not.



If you really want to delete it, have a backup and then delete both the gfid and any other hard links.
