I'am trying to define a procedure for me how to upgrade our lustre 1.6.6 running vanilla 18.104.22.168 kernels (gentoo distribution) to lustre 1.8.3 with SLES11 kernel 22.214.171.124.
Having said that i did it on a client and it works for the client side.
Before sending 100TB data down the drain i want to make sure that the general approach of upgrading "sounds" reasonable.
> You don't really need to rebuild e2fsprogs on every MDS/OSS, and in fact there is no reason to rebuild/reinstall e2fsprogs when updating Lustre - the same e2fsprogs is usable for all Lustre versions. Even if you are building your own Lustre you can probably use the pre-built e2fsprogs.
Hm, that sounds differently (to me) in the READMEs and on the Webpage for upgrading from 1.8.2 to 1.8.3.
I cannot not oversee myself what e2fs versions are really needed, as there are different packages for SLES and RH, so i try to stick to the docs as close as poss.
For upgrading i understand that i need to use "tunefs.lustre" et al and i'am not sure if these commands trigger some of the e2fsprogs.
Changes from v1.8.2 to v1.8.3
Recommended e2fsprogs version: 1.41.10-sun2
Thanks for your help.
