Hello,

I’m running Ubuntu 12.04. I need to rename my root logical volume group and it’s bootmanager/fstab accordingly.

Here is the output: I need to change the HP-TEST001 to PRODGROUP01. Please advice me.

Reduce system inode count

Leave a comment

By rupeshkp728

I have lots of space on my system.

Code:
linux-e30c:~ # df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 41G 3.4G 35G 9% /
/dev/sda3 91G 36G 51G 42% /home
/dev/sda2 99G 3.4G 91G 4% /usr

But still somehow the inode count has almost finished up and some times I am not able to create files.

Code:
linux-e30c:~ # df -ih
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/sda1 2.6M 2.6M 12K 100% /
/dev/sda3 5.8M 109K 5.7M 2% /home
/dev/sda2 6.3M 143K 6.2M 3% /usr

I tried deleting many files especially of small sizes.
Is there any way(other then to format the sda1) out of this issue to decrease the inode count?

Trouble with .tar creation over NFS mount

Leave a comment

By ikn3

Hello,

I am trying to backup a directory to an NFS mount. But after mounting the “tar” command is failing.

1. Created folder for mount point: test1
2. Mounted desired mount:
[root@server_name1 ~]# mount -t nfs server_name2:/backup/WMSAPP_backup -w /test1/
[root@server_name1 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVolRoot
19G 14G 4.1G 78% /
/dev/mapper/VolGroup00-LogVolTmp
9.5G 3.9G 5.1G 44% /tmp
/dev/mapper/VolGroup00-LogVolVar
4.8G 574M 4.0G 13% /var
/dev/mapper/VolGroup00-LogVolApps
99G 14G 81G 15% /apps/scope
/dev/sda1 996M 41M 904M 5% /boot
tmpfs 7.9G 0 7.9G 0% /dev/shm
server_name2:/backup/WMSAPP_backup
1008G 80G 878G 9% /test1

[root@servera-name1 ~]# tar cvf /test1/app_scope.tar /apps/scope/
tar: /test1/app_scope.tar: Cannot open: Permission denied
tar: Error is not recoverable: exiting now

A. Is there a different way of mounting where we can pass credentials. I read somewhere that we do not need credentials to mount as NFS.

B. Is there a different tar option that we can use…

THanks in advance for help.

Rsync size descrepancies

Leave a comment

By westmoreland

I’m using rsync to transfer data from one system (nfs01) to another (nfs02) but I’m seeing 28GB more data on the target than what’s on the source. The source and target filesystems are both 138 GB. The source shows 100GB used and after running rsync the target shows 128 GB used. Shouldn’t they be the same? As you can see below, three subfolders on the target system are each about 10GB larger than the source. I’m cluless, any help would be appreciated.

I’m running this rsync command on the target system (nfs02):

Code:
rsync -avr --delete root@nfs01r5v.lamar.edu:/bannertreedev/ /bannertreedev/

The source:

LVM Memory Usage

Leave a comment

By ikn3

Hello
I am using LVM to create volumes.

After creating the volumes using “lvcreate” and then formating them as “ext3”.
I mounted these volumes to find around 40 -50GB space wasted.

Any suggestions why?

# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sdb1 111G 16G 90G 15% /
/dev/sda1 99M 24M 71M 25% /boot

By karthikeayan

I am trying a script which will alert if disk space crosses some threshold, i googled it and got some scripts already, but they are not working with my server.

The problem is, my filesystem names are big, so the sizes are moving to the second line. just like below

any ideas? thanks in advance

user@host:/ta/folder/folder/tmp> df -h
Filesystem Size Used Avail Use% Mounted on
/dev/folder/folder/folder

Help with new disk but don't know how to add

Leave a comment

By samnyc

Hi,

This Linux server is a VM, on the VMware, I added new disk for this system. I was not able to see the new disk. I did try the scan command but didn’t work. I then rebooted the system. Now when I do

Code:

fdisk -l
Disk /dev/sda: 161.0 GB, 161061273600 bytes
255 heads, 63 sectors/track, 19581 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 268 2048287+ 82 Linux swap / Solaris
/dev/sda3 269 19581 155131672+ 83 Linux

On the Vmware, I added another disk for 150 Gig.

Here is the output from df -h

Code:

df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 144G 135G 1.9G 99% /
/dev/sda1 99M 26M 68M 28% /boot
tmpfs 942M 0 942M 0% /dev/shm

where is my new disk? how do I add that.
