Thank you linuxcricket!!

I tried setting the SELinux context as that of /var, but I still got permission denied while trying to set quota.

Code:
# chcon --reference=/var /u02
# r ls
ls -ldZ /u02
drwxr-xr-x. root root system_u:object_r:var_t:s0       /u02
# quotacheck -cug /u02
quotacheck: Cannot rename new quotafile /u02/aquota.user.new to name /u02/aquota.user: Permission denied
quotacheck: Cannot rename new quotafile /u02/aquota.group.new to name /u02/aquota.group: Permission denied

The system is registered with RedHat. But, I need to go through a lot of approval processes to log a ticket with RedHat support.

Anyways, I dug deeper and went through AVC denials by doing this:
Code:
sealert -a /var/log/audit/audit.log

It showed me the solution as:
Code:
SELinux is preventing /sbin/quotacheck from write access on the directory /u02.

*****  Plugin restorecon (82.4 confidence) suggests  *************************

If you want to fix the label.
/u02 default label should be default_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /u02

*****  Plugin file (7.05 confidence) suggests  *******************************

If this is caused by a newly created file system.
Then you need to add labels to it.
Do
/sbin/restorecon -R -v /u02

*****  Plugin file (7.05 confidence) suggests  *******************************

If you think this is caused by a badly mislabeled machine.
Then you need to fully relabel.
Do
touch /.autorelabel; reboot

*****  Plugin catchall_labels (4.59 confidence) suggests  ********************

If you want to allow quotacheck to have write access on the u02 directory
Then you need to change the label on /u02
Do
# semanage fcontext -a -t FILE_TYPE '/u02'
where FILE_TYPE is one of the following: boot_t, root_t, tmp_t, usr_t, var_t, mail_spool_t, etc_t, mqueue_spool_t, var_spool_t, home_root_t.
Then execute:
restorecon -v '/u02'


*****  Plugin catchall (1.31 confidence) suggests  ***************************

If you believe that quotacheck should be allowed write access on the u02 directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep quotacheck /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

I executed this:
Code:
grep quotacheck /var/log/audit/audit.log | audit2allow -M mypol
semodule -i mypol.pp

And it worked. I could run the quotacheck command without any problem. Thanks for your time to post here.

quotacheck

quotacheck(1M)						  System Administration Commands					    quotacheck(1M)

NAME

       quotacheck - ufs file system quota consistency checker

SYNOPSIS

       quotacheck [-fp] [-v] filesystem...

       quotacheck -a [-fpv]

DESCRIPTION

       quotacheck  examines  each  mounted  ufs file system, builds a table of current disk usage, and compares this table against the information
       stored in the file system's disk quota file. If any inconsistencies are detected, both the quota file and the current system  copy  of  the
       incorrect quotas are updated.

       filesystem is either a file system mount point or the block device  on which the file system resides.

       quotacheck  expects  each file system to be checked to have a quota file named quotas in the root directory. If none is present, quotacheck
       will not check the file system.

       quotacheck accesses the character special device in calculating the actual disk usage for each  user.  Thus,  the  file	systems  that  are
       checked should be quiescent while quotacheck is running.

OPTIONS

       The following options are supported:

       -a	Check the file systems which /etc/mnttab indicates are ufs file systems.  These file systems must be read-write mounted  with disk
		quotas enabled, and have an rq entry in the mntopts field in /etc/vfstab.

       -f	Force check on file systems with logging enabled. Use in combination with the -p option.

       -p	Check quotas of file systems in parallel. For file systems with logging enabled, no check is performed unless  the  -f	option	is
		also specified.

       -v	Indicate the calculated disk quotas for each user on a particular file system. quotacheck normally reports only those quotas modi-
		fied.

USAGE

       See largefile(5) for the description of the behavior of quotacheck when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

FILES
