<br>
Thanks for your information, which is very useful for me.<br>
<br>
I tried to use volume level worm feature and file level worm feature,<br>
and I think file level worm feature is seemly matching my needs.<br>
But I find it cannot work with samba. (volume level worm feature is OK)<br>
<br>
I mounted worm_vol on samba and setup samba server by the following configuration.<br>
[gluster-worm_vol]<br>
comment = For samba share of volume worm_vol<br>
vfs objects = glusterfs<br>
glusterfs:volume = worm_vol<br>
glusterfs:logfile = /var/log/samba/glusterfs-worm_<wbr>vol.%M.log<br>
glusterfs:loglevel = 7<br>
path = /<br>
read only = no<br>
guesn ok = yes<br>
kernel share modes = no<br>
<br>
The following error has been reported when I set the feature on the volume.<br>
[root@node mnt]# gluster vol set worm_vol features.worm-file-level on<br>
volume set: failed: One of the client <a href="http://127.0.0.1:1023" rel="noreferrer" target="_blank">127.0.0.1:1023</a> is running with op-version 30703 and doesn't support the required op-version 30800. This client needs to be upgraded or disconnected before running this command again<br></blockquote><div>The file level worm feature is implemented in glusterfs-3.8 but on your machine <a href="http://127.0.0.1:1023">127.0.0.1:1023</a> you are running glusterfs-3.7 (which is EOL). You should update the machines to have glusterfs 3.8 or above to avail this feature. And it is recommended to have all the machines running the same version of gluster.<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
<br>
Other features of worm can be setted without error.<br>
[root@ node mnt]# gluster vol set worm_vol features.default-retention-<wbr>period 30<br>
volume set: success<br></blockquote><div>This was successful because we do not check for the op-version when when setting this configurable.<br><br></div><div>HTH,<br></div><div>Karthik<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

The glusterd log shows as following:<br>
[2021-07-25 06:41:09.078135] I [MSGID: 106022] [glusterd-handshake.c:803:_<wbr>client_supports_volume] 0-glusterd: Client <a href="http://127.0.0.1:1017" rel="noreferrer" target="_blank">127.0.0.1:1017</a> (1 -> 30703) doesn't support required op-version (30800). Rejecting volfile request.<br>
<br>
The version info is as following:<br>
samba-vfs-glusterfs-4.4.4-14.<wbr>el7_3.x86_64<br>
glusterfs-3.10.3.tar.gz<br>
<br>
Can you give me some suggestion? Thanks!<br>
