Hi Folks, I've faced error while trying to remove an LVM from the server. The exact LVM error will be "Logical volume vmxxxx_img is used by another device" on executing the lvremove command. Feel free to remove the following steps to remove the LVM from the server. Note: Please remember to replace <id> with your  VMID in the below section. ---------------------------------------------------------- dmsetup ls dmsetup info -c xen-vm<id>_img dmsetup remove xen-vm<id>_img lvremove -f /dev/xen/vm<id>_img ----------------------------------------------------------

Cheat sheet for Hardware RAID health check - Megaraid, Adaptec, 3wareraid and HPraid.

Hi Folks, In another post " raid type " I've mentioned how to find if the server is running with Software or Hardware RAID. Here, we can go ahead and check the health of the Hardware RAID array in the server. The first thing we need to detect is the controller in which the raid is configured and you can easily get it from the another post that I mentioned earlier.

This will show the raid controller running on the server. The different types of controller I've worked with includes a. Megaraid which uses megacli b. Adaptec which uses arcconf . c. 3ware raid which uses tw_cli d. HPraid which uses hpacucli . How to check the Megaraid array health status? The Megaraid is usually installed in the /opt/MegaRAID and you can execute the following command to verify the health of the arr
