Subject: LU-7472 tests: Allows to specify IOR block size with suffix
X-Git-Tag: 2.8.57~38
X-Git-Url: https://git.whamcloud.com/?a=commitdiff_plain;h=refs%2Fchanges%2F54%2F17354%2F7;p=fs%2Flustre-release.git

LU-7472 tests: Allows to specify IOR block size with suffix

Added a variable io_blockUnit which can
be set to K, M or G and adjust the IOR block sizes.
Modified to keep m as the default option. Default block
size for IOR tests would be 6MB.

Test-Parameters: trivial
Seagate-bug-id: MRP-2685
