Mozilla Thunderbird shows the error message: “There is not enough disk space to download new messages. Try deleting old mail, emptying the Trash folder, and compacting your mail folders, and then try again.”

You verify and there is plenty of disk space.

This is happening because Mozilla Thunderbird is a 32 bit application and your inbox folder has more than 2GB of email.

To solve your problem, create a new folder and then copy your email to it.
Delete your emails from the inbox and then run Compact Folders.
Close Mozilla Thunderbird and open it again. Your email should be downloading.

virbr0 is an ethernet bridge

You use brctl to manage the interface.
brctl is used to set up, maintain, and inspect the ethernet bridge configuration in the linux kernel

Verify if libvirtd is running

This is the default network set-up for the virtual machines

Stop the libvirtd service

I was migrating some LUNs to another storage.

After creating the LUNs with the same size, I intended to move the data to the new disk but I was getting there was insufficient free space

root@linux:~ # pvmove /dev/mapper/bkpcvrdd01 /dev/mapper/bkpcvrdd01newp1
Insufficient free space: 12800 extents needed, but only 12799 available
Unable to allocate mirror extents for pvmove0.
Failed to convert pvmove LV to mirrored

What happens is that the source disk is bigger than the new disk.

root@linux:~ # pvdisplay /dev/mapper/bkpcvrdd01 /dev/mapper/bkpcvrdd01newp1

Both are the same size but due to the physical structure, each disk shows a different size.

Run fdisk -l and observe the size. This is the disk after a LUN expansion.

root@linux:~ # fdisk -l /dev/mapper/bkpcvrdd01new

Disk /dev/mapper/bkpcvrdd01new: 54.2 GB, 54223962112 bytes
255 heads, 63 sectors/track, 6592 cylinders

To solve this problem I booted in single user mode and moved the script that sets the time

I have a HP Proliant server that is using hardware RAID for the boot disk but when I used hpacucli no status was shown

root@linux:~ # hpacucli ctrl all show config

Verified if I have RAID and the server model

root@linux:~ # dmidecode | grep -i proliant

I had hpacucli 8.70 and I read that old versions that causes problems like this. So I uninstalled

root@linux:~ # rpm -qa | grep hpacucli
hpacucli-8.70-8.0.i386

root@linux:~ # rpm -e hpacucli

And installed the newest version

DOWNGRADE NOTE: To downgrade this application to any version prior to 9.10.x.x, the current RPM must be manually uninstalled using the “rpm -e” command before any prior versions can be installed.

LOCKING NOTE: The locking mechanism starting with versions 9.10.X.X, are not compatible with prior versions of the applications. Therefore, mixing older and newer versions of the various applications (ACU, HPACUCLI, HPACUSCRIPTING) is not recommended.

Running Storage Foundation Basic installer was giving me an error message saying perl was not found

root@centos6veritas:/tmp/veritas/dvd3-sfbasic/rhel6_x86_64# ./installer
Error: Cannot find perl to execute ./installer

The installer script checks the binary on the directory of your distribution/perl. Since this is not a genuine Red Hat Enterprise Linux, a workaround is needed.

Thanks to the Symantec Storage Foundation 6.2 Release Notes – Linux: Storage Foundation Basic cannot be installed on the Oracle Enterprise Linux platform (3651391) I found why the installer wasn’t working.

But in the end the installer will refuse to install and quit because it expects a Red Hat Enterprise Linux or Oracle Linux

root@fedora:~ # vi /etc/yum.repos.d/google-chrome.repo

baseurl=http://dl.google.com/linux/chrome/rpm/stable/x86_64
enabled=1
gpgcheck=1
gpgkey=https://dl-ssl.google.com/linux/linux_signing_key.pub

Then run again yum update or yum install google-chrome-stable and it will automatically import the public key

When listing the disks used by LVM and it shows only dm, you can make it display the multipath friendly name

root@linux:~ # pvs

/dev/cciss/c0d0p2 rootvg lvm2 a- 135.69G 11.69G

/dev/dm-7 softwarevg lvm2 a- 100.00G 0
/dev/dm-8 softwarevg lvm2 a- 50.00G 0

Edit file /etc/lvm/lvm.conf and tell LVM to not use the cache file. Set write_cache_state to 0

root@linux:~ # vi /etc/lvm/lvm.conf
write_cache_state = 0

And delete the cache file

root@linux:~ # rm /etc/lvm/.cache

It should be displaying with the friendly names

If you need to map, go to /dev/mapper and do a long listing. Search for the number after the 253,. Eg. dm-33 is the sfwdisk05_NEW1

extend the usable space to fill the disk.

There should be a difference in cylinders and blocks between the two disks that is causing this message

I was trying to create the device file partition but I was receiving an error message

root@linux:~ # kpartx -a /dev/mapper/mpathm
device-mapper: create ioctl failed: Device or resource busy

The disk already had a partition. Let’s use dmsetup to see what we have

root@linux:~ # dmsetup ls | grep mpathm
mpathm-part1 (253, 38)
mpathm (253, 32)

We already have a mpathm registered so we need to remove

root@linux:~ # dmsetup remove mpathm-part1

Then retry
