Need assistance with Linux script to calculate free space on drive
Hello,
I am running into some limitations (...by design) with the XenCenter and Xenserver (Citrix Hypervisor) the issue I am facing is that when I am using GFS2 with the shares storage drives the XenCenter (mananagement console) doesn't seem to calculate the free space that's available for that particular shared storage drive.
That being said, I am looking to get some assistance writing a quick script to check the available space on a drive or file system and email if the system free space is below 20%. I will run the script a chron job every hour.

Just run the following...
Both these will produce human (-h) output, then you can trigger an email if any mount point grows past a certain usage amount.
df -h
df -h -iBoth these will produce human (-h) output, then you can trigger an email if any mount point grows past a certain usage amount.
Best check both space (df -h) + inode usage (df -h -i).
Checking inode usage will normally only be required if you have many small files, like running an IMAP server.

Hello,
With df -h I don't see any of the storage repositories (file systems) that are block only the NFS ones.

Post your df -h output, along with name of mount point of interest.

Maybe automounting is in the mix...
Post the output of mount, something like /gfs (absolute path of mount point).

Sorry, what command would like to run to show the auto mounting?

FC is handled as a kind of SCSI, so your FC disk could very well be /dev/sda
fdisk -l /dev/sda - might show more info to determine this.
dmesg (shortly after booting, sometimes in /var/log/dmesg, search for the discovery recordss of the sda disk)
