[Gluster-users] Gluster CLI reference

[Nithya Balachandran]

Hi,

As part of our initiative to improve our docs, we have made a few changes
over the past few weeks. One of this is a CLI reference [1]. This is still
a WIP so not all commands have been documented.

Is this something you would find useful?
Would you like to see more information captured as part of this? If yes,
what else should we include?

Thanks,
Nithya

Re: [Gluster-users] gfid entries in volume heal info that do not heal

[Matt Waymack]

OK, so here’s my output of the volume info and the heal info. I have not yet 
tracked down physical location of these files, any tips to finding them would 
be appreciated, but I’m definitely just wanting them gone.  I forgot to mention 
earlier that the cluster is running 3.12 and was upgraded from 3.10; these 
files were likely stuck like this when it was on 3.10.

Hi Matt,

The files might be in split brain. Could you please send the outputs of these?
gluster volume info 
gluster volume heal  info
And also the getfattr output of the files which are in the heal info output 
from all the bricks of that replica pair.
getfattr -d -e hex -m . 

Thanks &  Regards
Karthik

Hi all,

I have a volume where the output of volume heal info shows several gfid entries 
to be healed, but they’ve been there for weeks and have not healed.  Any normal 
file that shows up on the heal info does get healed as expected, but these gfid 
entries do not.  Is there any way to remove these orphaned entries from the 
volume so they are no longer stuck in the heal process?

Thank you!

[Gluster-users] gfid entries in volume heal info that do not heal

[Matt Waymack]

Hi all,

I have a volume where the output of volume heal info shows several gfid entries 
to be healed, but they've been there for weeks and have not healed.  Any normal 
file that shows up on the heal info does get healed as expected, but these gfid 
entries do not.  Is there any way to remove these orphaned entries from the 
volume so they are no longer stuck in the heal process?

Thank you!
