Can't log into the webpage

That can't be true. I partitioned the drive to have a 40G hard drive.

Yes, but if you used the image supplied by Nagios, then that is the default space, you actually have to expand the / partition. There is a document somewhere on how to do that. I'll try and find it.

Not sure this is still good, can someone from Nagios confirm - http://assets.nagios.com/downloads/nagi ... M_Disk.pdf

Ok, thank you. Is that document on their site?

Since you have a LVM in place you will probably need to resize the volume.

It's pretty painless, just make sure you do backups first. A VM snapshot should do it.

Thank you for your help. I am able to log in now. I followed the directions to increase the LVM, but it is still showing the following:

[root@nagios ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup-lv_root
7.5G 7.1G 12M 100% /
tmpfs 7.8G 0 7.8G 0% /dev/shm
/dev/sda1 485M 50M 410M 11% /boot
[root@nagios ~]# df -i
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/mapper/VolGroup-lv_root
494832 95274 399558 20% /
tmpfs 2041672 1 2041671 1% /dev/shm
/dev/sda1 128016 44 127972 1% /boot
[root@nagios ~]#

Did you run the resizefs as well? You might have expanded the LVM itself but not the filesystem. Though I would expect that if you did this you would still be unable to log in.

Looks like to me it hasn't been resized. Looks like somehow 12 MEG became available which is just enough for things to seem to work.

Yes I have run resize2fs command, but reiserfs or the rest of the steps because it wouldn't let me.

[lmiltchev]

I've seen users copying/pasting the commands from the document:

Code: Select all

lvresize /dev/mapper/VolGroup00-LogVol00 /dev/sda2

and

Code: Select all

resize2fs /dev/mapper/VolGroup00-LogVol00

This is just an example. You should probably substitute the "VolGroup00-LogVol00" with "VolGroup-lv_root" in your commands, since you have:

Code: Select all

/dev/mapper/VolGroup-lv_root

Please, backup before you do anything!

[ancovington]

Yes, I have been substituting with the correctly. Is this the output it should have:

[root@nagios ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup-lv_root
37G 7.1G 29G 21% /
tmpfs 7.8G 0 7.8G 0% /dev/shm
/dev/sda1 485M 50M 410M 11% /boot
/dev/mapper/VolGroup-lv_root
37G 7.1G 29G 21% /home
[root@nagios ~]# df -i
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/mapper/VolGroup-lv_root
2441712 95927 2345785 4% /
tmpfs 2041672 1 2041671 1% /dev/shm
/dev/sda1 128016 44 127972 1% /boot
/dev/mapper/VolGroup-lv_root
2441712 95927 2345785 4% /home

It looks much better now. Let me know if you want me to keep this topic still open for a while, or I can lock it as "resolved". Thanks!
