Xavi,
We are encountering errors for different kinds of FOPS.
The open failed for the following file:
cvd_2017_01_10_02_28_26.log:98182 1f9fe 01/10 00:57:10 8414465

OperationFlag=0xC1, PermissionMode=0x1FF}
I've attached the extended attributes for the directories
/ws/glus/Folder_07.11.2016_23.02/CV_MAGNETIC/V_8854974/ and
/ws/glus/Folder_07.11.2016_23.02/CV_MAGNETIC/V_8854974/CHUNK_51342720
from all the bricks.
The attributes look fine to me. I've also attached some log
cuts to illustrate the problem.
I need the extended attributes of the file itself, not the parent
directories.
Xavi
Thanks and Regards,
Ram

Hi Ram,
the error is caused by an extended attribute that does not match on all
3 bricks of the disperse set. Most probable value is trusted.ec.version,
but could be others.
At first sight, I don't see any change from 3.7.8 that could have caused
this. I'll check again.
What kind of operations are you doing ? this can help me narrow the search.

Xavi,
Thanks. If you could please explain what to look for in the
extended attributes then I will check and let you know if I find
anything suspicious. Also we noticed that some of these operations
would succeed if retried. Do you know of any communicated related errors
that are being reported/triaged.
Thanks and Regards,
Ram

Xavi,
Please find attached the extended attributes for a
directory from all the bricks. Free space check failed for this with
error number EIO.
What do you mean ? what operation have you made to check the free
space on that directory ?
If it's a recursive check, I need the extended attributes from the
exact file that triggers the EIO. The attached attributes seem
consistent and that directory shouldn't cause any problem. Does an 'ls'
on that directory fail or does it show the contents ?
Xavi
Thanks and Regards,
Ram

Hi Ram,
can you execute the following command on all bricks on a file that is
giving EIO ?
getfattr -m. -e hex -d <path to file in brick>

Xavi,
We have been running 3.7.8 on these servers. We upgraded
to 3.7.18 yesterday. We upgraded all the servers at a time. The
volume was brought down during upgrade.

Hi Ram,
how did you upgrade gluster ? from which version ?
Did you upgrade one server at a time and waited until self-heal
finished before upgrading the next server ?

We upgraded to GlusterFS 3.7.18 yesterday. We see lot of
