changing ownership on NFS shared ZFS storage - quota exceeded

I have very bizarre problem. I have CentOS server 6.10 and ZFS storage. Now storage is configured long time ago by someone, and I found out that for certain user there is a quota set. when I check on the filesystem I get output this zfs# zfs get quota volume/local/default/users NAME PROPERTY VALUE SOURCE volume/local/default/users quota none default so from this I can see that on parent folder there is no quota set, but when I check particular user by using this command: zfs# quota -v user Disk quotas for user (uid 1000): Filesystem usage quota limit timeleft files quota limit timeleft /export/mail 930552 10485760 10485760 - - - - - /export/users 2147483646 31457280 31457280 NOT STARTED - - - - so I can see that user > user has set quota. Now, this ZFS has been mounted on CentOS 6.10 with this values in /etc/fstab: zfs.mydomain.com:/export/users /users nfs defaults,_netdev 0 0 and I can access /users folder. The problem starts when I want to use chown command: chown -R test:grp /home/user/mnt/child_fldr Please note that the "test" user is NIS user which I also tested with ypcat passwd, if I can get list of all users from NIS. (and I do), so this is not a problem. The output of the error is: > chown: changing ownership of `/home/user/mnt/child_fldr/temp': Disk quota exceeded Now to be even more confused, when I try to change an ownership by using local user account, I have no problem of changing it, but using NIS user, I get some dumb Disk quota exceeded message. For the test, I have tried to remove "quotas" file in the parent directory of child_fldr, and remount drive, with no success. Also on ZSF I tried to completely remove quota for testing by using quotaoff -a command, again still no progress. How can I solve my problem to be able again to change ownership of the directory?
