## Formula in determining the disk space for ignite server

hi everybody,

i want to know what would be a formula in computing the right amount of disk space in a ignite server.
example: i have 3 servers as ignite client, 1 having 200gb space and the other 2 having 50gb each...how do i compute the desired space allocation for my ignite server to accommodate these clients?

Esmayatin ,

- Run his formula on each client system, and determine the vg00 used space , multiply by 2 . And add for all the three clients space , that much + few extra percentage say 25% , that would give you the estimate of the space you needed for the ignite server.

# bdf | grep -v File | grep vg00 | grep -v ":" | grep % | cut -c 19- | awk '{a+=\$2}END{printf "%.f\n",a}' | awk '{print \$0/(1024*1024) "GB"}'

Considering you are using inc_entire=vg00 with make_net_recovery command.

Enjoy, Have fun!,

I'm curious about why do we have to multiply each server's sum into 2?

then another extra 25%.... this is a lot.

Size of ignite file system depend on like :

#how many version/copy of ignite of client server you want to keep of ignite server.
#multiple of two may be for mirror concept /protection that may be provided to FS.

#How frequently the size of ignite File system grow.

Esmayatin,

> I'm curious about why do we have to multiply each server's sum into 2?

This is because you will have one old good copy , + one latest copy ( 2 copy you can keep there) . Few extra percentage kept in buffer , keeping in mind about the filesystem data growth. As the filesystem(s) data increases the size of the image also need more space,so to make sure make_net_recovery happens successfully.

Btw if you want to delete the old archive and to take a fresh make_net_archive every time, that will be the only one copy, so 1 time space would be enough.
