Thanks for responding @jlliagre and @radoulov (bouncing apache or unmounting and mounting zfs fs are last options for me)...
I usually truncate the file after making a copy, but someone before me deleted the file directly. Now, when I do du -skh /export/home/ajb it shows around 70M but df and zfs list shows about 9.7g which is 100%. I have seen this discrepancy between du and df in UFS for which I use the following solution
Sorry it wont let me post a link to the source, for the source please google for
Discrepancies Between df And du Outputs
Code:
1. Find the file which has been unlinked through the procfs interface
# find /proc/*/fd \( -type f -a ! -size 0 -a -links 0 \) -print | xargs \ls -li
415975 --w------- 0 user group 2125803025 Oct 15 23:59 /proc/1252/fd/3
2. Eventually, get more detail about it:
1252
3.Check to see if you can understand what is the content of the unlinked file:
# tail /proc/1252/fd/3

4.You can correlate the size of the removed, but always referenced, file to the space accounted from the du and df tools:
# df -k /path/to
Filesystem kbytes used avail capacity Mounted on
/dev/md/dsk/d5 6017990 5874592 83219 99% /path/to
# du -sk /path/to
3791632 /data
# echo "(5874616-3791632)*1024" | bc
2132975616
5. So, we now found the ~2GB log file which was always opened (used) by a process. Now, there are two solutions to be able to get back the freed space:
Truncate the unlinked file (quick workaround).
Simply restart properly the corresponding program (better option).
But I don't know if that'll work for a zfs filesystem.... Do you know any procedure like the one above where I can truncate the links which are holding up the space?

Hi,
If I change date and time in global zone, then it will affect in non global zones.
During this process what files will get affect in non global zones and which mechanism it's using to change.

Hi, hoping someone can help, its been a while since I used Solaris.
After creating a NGZ (non global zone), the NGZ can access the GZ (Global Zone) and the GZ can access the NGZ (using ssh, zlogin)
However, the NGZ cannot access any other netwqork devices, it can't even see the default router

AMZFS-SENDRECV(8) System Administration Commands AMZFS-SENDRECV(8)NAME
amzfs-sendrecv - Amanda script to create zfs sendrecv
DESCRIPTION
amzfs-sendrecv is an Amanda application implementing the Application API. It should not be run by users directly. It create a zfs snapshot
of the filesystem and backup the snapshot with 'zfs send'. Snapshot are kept after the backup is done, this increase the disk space use on
the client but it is neccesary to be able do to incremental backup. If you want only full backup, you can disable this feature by setting
the KEEP-SNAPSHOT property to 'NO'. Only the restoration of the complete backup is allowed, it is impossible to restore a single file.
The application is run as the amanda user, it must have many zfs priviledge:
zfs allow -ldu AMANDA_USER mount,create,rename,snapshot,destroy,send,receive FILESYSTEM
Some system doesn't have "zfs allow", but you can give the Amanda backup user the rights to manipulate ZFS filesystems by using the
following command:
usermod -P "ZFS File System Management,ZFS Storage Management" AMANDA_USER
This will require that your run zfs under pfexec, set the PFEXEC property to YES.
The format of the diskdevice in the disklist (DLE) must be one of:
Desciption Example
-----------------
Mountpoint /data
ZFS pool name datapool
ZFS filesystem datapool/database
ZFS logical volume datapool/dbvol
The filesystem doesn't need to be mounted.
PROPERTIES
This section lists the properties that control amzfs-sendrecv's functionality. See amanda-applications(7) for information on the
Application API, application configuration.
DF-PATH
Path to the 'df' binary, search in $PATH by default.
KEEP-SNAPSHOT
If "YES" (the default), snapshot are kept after the backup, if set to "NO" then snapshot are no kept and incremental backup will fail.
ZFS-PATH
Path to the 'zfs' binary, search in $PATH by default.
PFEXEC-PATH
Path to the 'pfexec' binary, search in $PATH by default.
PFEXEC
If "NO" (the default), pfexec is not used, if set to "YES" then pfexec is used.
EXAMPLE
In this example, a dumptype is defined to use amzfs-sendrecv application to backup a zfs filesystem.
define application-tool amzfs_sendrecv {
comment "amzfs-sendrecv"
plugin "amzfs-sendrecv"
#property "DF-PATH" "/usr/sbin/df"
#property "KEEP-SNAPSHOT" "YES"
#property "ZFS-PATH" "/usr/sbin/zfs"
#property "PFEXEC-PATH" "/usr/sbin/pfexec"
#property "PFEXEC" "NO"
}
define dumptype user-zfs-sendrecv {
program "APPLICATION"
application "amzfs_sendrecv"
}
