Space Allocation Issue

[wish_1]

Dear All

We are having HP 9000 L with 2 Node Cluster. Each node is having 8GB Disk and array of 8GB X3 Disk also. With HP-UX B.11.00 ver and Oracle 8i.

We have plans of, using one of the nodes as standalone. I am facing problem of organizing space.

I am pasting bdf listing of node A as follows

/dev/vg00/lvol3 4063232 3836286 214975 95% /
/dev/vg00/lvol1 99669 54381 35321 61% /stand
/dev/vg00/lvol4 2617344 1665779 899840 65% /oracle


bdf listing of node B as follows
# bdf
Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol3 4063232 3800837 246044 94% /
/dev/vg00/lvol1 99669 54127 35575 60% /stand
/dev/vg00/lvol4 2617344 413169 2068213 17% /oracle


Please let me know about space that could be released from Node A. What files that can be deleted from root(/), /stand

Kindly help me at the earliest.

Thanks & Regards

Hi Wish ,

Perhaps you cannot delete anything from /stand , as /stand contains all kernel configuration files.


1. Quickly you can try :
# ls -lR | sort +4 -5nr | more
(To see the largest files.


2. Check for big files on / (root)

# cd /
# find . -type f -xdev -exec ls -l {} \; > /tmp/out.txt
# cat out.txt | sort +4 -5nr > out1.txt

Check out1.txt file , all largest file will be listing from the top , and what you can delete you can determine.


hth,
Raj

Is not easy to say what can be erased, you should find out the biggest files, and then verify if can be deleted.

Use the following command:

find / -xdev -type f -exec ls -la {} \; | sort +5 -nrb > /tmp/find.out

Examine the file and post the biggest files to verify that can be deleted if you are unsure.

It appears that someone overrode the 'normal' disk volume layout and put everything in / (4 Gb), a very bad idea for a production server running something like Oracle. /stand is fine, but / needs so much re-arranging, that you will likely need to re-install. 4Gb sounds about right as the total for all filesystems in a typical HP-UX system.

If there are indeed other mounted filesystems such as /var and /usr, then 4Gb is WAY too large and something does not belong in /. The typical size for / is 100-250 megs. So do not look for big files. Instead, analyze all the directtories and post the top 10 using:

du -kx / | sort -rn | head

Once the largest directory is located, space problems can be determined easily. The largest directories in / will be /sbin and /etc.

Hi Wish,
check also if under "/" file system exist
core file .
