Re: File\Directory not healing

David Dolan <daithidolan@xxxxxxxxx> · Thu, 23 Feb 2023 12:48:46 +0000

Just to confirm I've got this correct?
So I'll move the directory with the different gfid on the Arbiter brick to somewhere else
I then touch this directory on another brick(software is not sensitive to atime update)

I guess the healing should then take place automatically?

Thanks
David

  Hi Strahil,
The output in my previous email showed the directory the file is located in with a different GFID on the Arbiter node compared with the bricks on the other nodes.

Based on that, do you know what my next step should be?

Thanks
David

sorry I didn't receive the previous email.I've run the command on all 3 nodes(bricks). See below. The directory only has one file.
On the Arbiter, the file doesn't exist and the directory the file should be in has a different GFID than the bricks on the other nodes

Use getfattr and identify if the gfid mismatch. If yes, move away the mismatched one.
In order a dir to heal, you have to fix all files inside it before it can be healed.

                I've touched the directory one level above the directory with the I\O issue as the one above that is the one showing as dirty.It hasn't healed. Should the self heal daemon automatically kick in here?

Is there anything else I can do?

Thanks
David

You can always mount it locally on any of the gluster nodes.

  HI Strahil,
Thanks for that. It's the first time I've been in this position, so I'm learning as I go along.

Unfortunately I can't go into the directory on the client side as I get an input/output error
Input/output error
d????????? ? ?      ?        ?            ? 01

Setting blame on client-1 and client-2 will make a bigger mess.Can't you touch the affected file from the FUSE mount point ?

  Hi All. 

Hoping you can help me with a healing problem. I have one file which didn't self heal.
it looks to be a problem with a directory in the path as one node says it's dirty. I have a replica volume with arbiter
This is what the 3 nodes say. One brick on each
Node1getfattr -d -m . -e hex /path/to/dir | grep afrgetfattr: Removing leading '/' from absolute path namestrusted.afr.volume-client-2=0x000000000000000000000001trusted.afr.dirty=0x000000000000000000000000Node2getfattr -d -m . -e hex /path/to/dir | grep afrgetfattr: Removing leading '/' from absolute path namestrusted.afr.volume-client-2=0x000000000000000000000001trusted.afr.dirty=0x000000000000000000000000Node3(Arbiter)getfattr -d -m . -e hex /path/to/dir | grep afrgetfattr: Removing leading '/' from absolute path namestrusted.afr.dirty=0x000000000000000000000001
Since Node3(the arbiter) sees it as dirty and it looks like Node 1 and Node 2 have good copies, I was thinking of running the following on Node1 which I believe would tell Node 2 and Node 3 to sync from Node 1
I'd then kick off a heal on the volume
setfattr -n trusted.afr.volume-client-1 -v 0x000000010000000000000000 /path/to/dirsetfattr -n trusted.afr.volume-client-2 -v 0x000000010000000000000000 /path/to/dir
client-0 is node 1, client-1 is node2 and client-2 is node 3. I've verified the hard links with gfid are in the xattrop directory
Is this the correct way to heal and resolve the issue? 

Thanks
David
