Hello this is my first time posting a support topic in here so apologize if there is any mistake
Long time ago I set-up nextcloud server on Ubuntu 16.04 LTS,
My setup was Using Server for the nextcloud installation and using QNAP with NFS mount as a data folder on nextcloud
this is the setup for /etc/exports from NAS
"/share/CACHEDEV1_DATA/Web" 192.168.100.7(sec=sys,rw,async,wdelay,insecure,no_subtree_check,no_root_squash,fsid=e0cd2aff70d6e8230b19741d75feef97)
and in my old ubuntu server, this is the setup for fstab:
192.168.100.81:/share/CACHEDEV1_DATA/Web/nextcloud /var/www/html/nextcloud/data nfs defaults 0 0
and everything went well with my old ubuntu server,
now the problem, because Ubuntu 16.04 is EOL and i need to consolidate all my apps to one server I need to migrate my nextcloud installation to another server which is using Almalinux 8 and also to update my nextcloud version to the recent (after I successfully migrate it of course)
Already read all the documentation related to migration, and basically everything from sync all the necessary files from old server to the new server and upload the database is success,
Nextcloud version (eg, 20.0.5): 15.0.X
Operating system and version (eg, Ubuntu 20.04): Almalinux 8
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.x Latest
PHP version (eg, 7.4): 7.2.X Latest
The issue you are facing:
after following the step by step migration when I run the nextcloud, return in internal error and on the nextcloud.log there is no log created, so my guest would be permission, and suddenly I notice that after I mount nfs4 of my qnap into my almalinux server all the file and folder inside data folder using old uid and gid from ubuntu uid=33 (www-data) and gid=33 (www-data), and centos based doesnt have user id 33 and gid 33 translate to group ‘tape’
When i unmount the NFS, nextcloud template load and data folder error occurred which is already predicted, and when try to re-mount again, the internal server error appeared again.
So my question:
my initial thought would be user and group that mismatch from my old server to my new server, if let say I just replace all the user and group from let say to uid=1000 and gid=48 in my QNAP NAS to match for my new centos based server, is it possible? and would this process will damage my nextcloud accessibility to the data?
or there is another simple method to make NFS data accessible with the new server?
UPDATE:
I try to change manually update my appdata folder consist of themes and .ocdata to 1000:48 and nextcloud load successfully to maintenance mode, but Im still afraid to disable maintenance mode, since the rest of the file still in user;group=33:33
any hints will be appreciated, thank you
here is the log from my nextcloud.log (after I manually chown to 1000:48):
