Hi Andrew,
There are no such things as a filesystem version, as a filesystem is made of
MDTs, OSTs and clients. Each of them could have different Lustre versions (even
if running too much different lustre versions between MDT and OST is not really
supported).
So, to get the Lustre version, you should check server versions, with this
command by example:
$ lctl get_param *.*.import | grep target_version
The local Lustre client version could be read with
$ lctl get_param version

Hi All,
Is there a trivial command to determine the server side version of
lustre (in my case, trying to confirm what types of quotas are allowed
(project - 2.10+, default - 2.12+) ?
I was hoping there'd be something in lfs, such as lfs getname
--version which would ideally spit out something like
$ lfs getname --version
fs1-ffff9920dde7d000 /fs1 2.10.4
testfs-ffff992073597800 /testfs 2.12.5
but that's wishful thinking :-) as lfs --version merely gives me the
client version as expected
Is this something that's fairly trivial and I'll open a jira ticket
for the request - I know it's done at mount time as the kernel can log
kernel: Lustre: Server MGS version (2.5.1.0) is much older than
client. Consider upgrading server (2.12.5)
Many thanks
Andrew
