Maximum Stripe Size Using LMV

[Michael Bertrand]

When creating a file system using LVM, is there a maximum stripe size or a limitation you can use?

[Paul Sperry]

When striping with LVM, one should make sure that the file system block size and the LVM stripe size are identical. This will aid performance.

Here's a tehnical  paper on LVM limits too.

Hi Michael:

The manpages for 'lvcreate' document the limits for each geometry.

Stripe_size should be a power of 2 in the range 4 to 32768.

Stripes must be in the range 2 to the number of disks in the current volume group. This is the number of disks to stripe across.

Regards!
