Hi,

i hope it's ok to ask here, if not tell me.
I know there is a ML ocfs2-user, but it has such low traffic (no E-Mail in the second half of 2020 !) that it doesn't help much.
I have a two-node HA-cluster with pacemaker. My ressources are virtual domains.
The virtual disks of the domains are raw files on an OCFS2 volume on a SAN.
Each evening the domains are shutdown to make a consistent reflink of each raw file which i copy afterwards in the background to a CIFS share.
In my syslog appears quite often the mentioned error:

I grepped around in the sources but my last touch with C is 25 years ago.
I "think" the call of the function ocfs2_reflink_ioctl returns a "-17", which indicates clearly that someting is wrong.
But i have no idea what.
My systems are SLES 12 SP5 with kernel 4.12.14-122.46-default and ocfs2-tools-1.8.5-3.3.1.x86_64.

The point is that i have trouble starting some domains after creating the reflinks, some fail occasionally and boot e.g. into emergency mode 
and i try to narrow down the problem.

I'd appreciate very much your help.

Thanks.

 #define EEXIST          17      /* File exists */

You may already have the file created from the other node.

Hi Wengang,

thanks for your help.

The reflink is created via:
reflink -fv /path/to/domain.raw /mnt/ocfs2/reflink

Of course this file exists already because the skript ran also one day before.
But from which node the previous one was created is unpredictable, it might be the same
but also the other one.

Is the message severe or don't i have to bother about it ?

Thanks.

Hi Bernd,

It looked you run reflink to clone the file from two node 
simultaneously? then reflink will fail from one node, since the 
destination file has existed.


Thanks
Gang

OCFS2 is a shared-storage cluster FS.  For the reflinks, you need and should create them only from one of the nodes. Don’t do duplicated work (reflink) on other nodes.

Hi Wengang,

thanks for your help.
Just to be sure that i understand you completely:
we reflink some raw file from host 1 and OTHER raw files (not the same !) from host 2.
Is that already a problem ? Or are you talking about reflinking the SAME file concurrently from both nodes ?

No, that’s not a problem.  Make sure your applications does the same as you want.
From the error message, your app could be creating duplicated reflinks from one or two nodes.
That’s what we can know by the error message. I am suspecting the problem is in your app, you could try to debug it.

Hi,

what we do is to overwrite the reflink from the day before with the current one, with the same name.
For this we use reflink -f. Could that be the culprit ?
Should we delete the old one before ? Or maybe use unique names for each reflink ?

Thanks.

I think you are doing so is to take a file snapshot. So a unique name
for each snapshot looks more reasonable, since you can find the most
suitable backup you want.
Generally filename + timestamp is commonly used for this situation.

Thanks,
Joseph

-f, --force                 remove existing destination files

-f option is used to remove the destination files if they already exist.

If you do see "reflink -f" returns -17 error, that could be an OCFS2 problem.
BTW, where comes your reflink command?  use
rpm -qf `which reflink`
to see that if you use rpm.

thanks,
wengang
