Glusterfind pre command fails
Version-Release number of selected component (if applicable):
Distro : RHEL7.7
Kernel version : 3.10.0-1061.el7.x86_64
Python 3.6.8
Gluster version : upstream at commit 8d55951 as shown below
# git branch -v
* master 8d55951 leases: re-alignment of structures
# gluster --version | head -1
glusterfs 8dev
How reproducible:
Easily
Steps to Reproduce:
1. Create and mount a volume replicated volume.
2. create a session as follows :
# glusterfind create s1 repvol
3. Update some files on the gluster client
4. fire the glusterfind pre command :
# glusterfind pre s1 repvol output.txt
===========================
Exact steps that I did :
===========================
1. Create a replicated volume.
2. Mount the volume on the client as follows :
# mount -t glusterfs 192.168.1.18:/repvol /mnt/t1
3. Create a few files on the mounted volume :
# cd /mnt/t1
# echo "hi" > file1
# echo "hi" > file2
4. Create a session on the gluster server :
# glusterfind create s1 repvol
192.168.1.22 - pre failed; stdout (including remote stderr):
b'192.168.1.22: /testxfs/brick-a1/brick Historical Changelogs not
available: [Errno 2] gf_history_changelog: No such file or directory\n'
stderr:
b''
192.168.1.18 - pre failed; stdout (including remote stderr):
b'Connection to 192.168.1.18 closed.\r\n'
stderr:
b'192.168.1.18: /testxfs/brick-a1/brick Historical Changelogs not
available: [Errno 2] gf_history_changelog: No such file or directory\r\n'
Generated output file /testxfs/output.txt
5. Create one more file on the client :
# echo "hi" > file3
6. Fire glusterfind pre command :
# glusterfind pre s1 repvol output.txt
Post command is not run after last pre, use --regenerate-outfile
7. Fire glusterfind post command :
# glusterfind post s1 repvol
Session s1 with volume repvol updated
8. Fire the glusterfind pre command :
# glusterfind pre s1 repvol output.txt
Generated output file /testxfs/output.txt
9. You can see the newly created file :
# cat /testxfs/output.txt
NEW file3
10. Now append the same file on the client :
# echo "hi" >> file3
11. On the server fire the glusterfind post command :
# glusterfind post s1 repvol
Session s1 with volume repvol updated
12. Now when pre command is fired we get the below error :
# glusterfind pre s1 repvol output.txt
192.168.1.22 - pre failed; stdout (including remote stderr):

Two things here:
1. glusterfind uses pyxattr and not xattr module. I think, it's taken care in
rpm install but on source install, it's taken fore python2. So install as below
if not installed.
#pip3 install pyxattr (for python3)
#pip install pyxattr (for python2)
And remove xattr module if installed. I think both share the same namespace
and might conflict.
#pip3 uninstall xattr (for python3)
#pip uninstall xattr (for python2)
2. There were issues w.r.t python2/python2 compatibility related dictionary and
bytes/string handling. The patch https://review.gluster.org/23993 fixes the
same.
