Re: [lustre-discuss] getcwd() fails

[Leonardo Saavedra]

you have to upgrade your kernel to kernel-3.10.0-1127.8.2.el7.x86_64.

The getcwd issue was fixed in :

[...]
- [fs] vfs: close race between getcwd() and d_move() (Miklos Szeredi)

Hi, Alex
Thanks for your suggestion.
I did some tests this weekend and found that  may be intel mpi's or 
vasp's issue.
When I ran another version of vasp which compiled with intel mpi 2017 
the error disappeared.

Then，I switched to the original version of vasp，errors occured.

I can not find any errors about lustre in that client.
Any more , in mds I can't find any errors about that client.

Any suggestions?



similar to
https://jira.whamcloud.com/browse/LU-12997 ?
the first comment in LU-12997 says it is a kernel bug.

Thanks,
Zam.

Re: [lustre-discuss] Running an older Lustre server (2.5) with a newer client (2.11)

Hey Lustre fans!

Is there anyone out there running Lustre server version 2.5.x with a 
Lustre client version 2.11.x? I'm curious if you are running this 
combination and whether or not you saw and gains or losses when you 
went to the newer Lustre client.


We were running Lustre 2.7 client before and just recently went to 
2.11. I'm trying to get a better understanding as to how common it is 
to have the version drift between the server and the client, as well 
as any positive or negative experiences.


it works, no problem at all, in your client's logs you'll see a message 
like:


---

[60011.029258] LNet: Added LNI 10.64.102.152@tcp [8/256/0/180]

It won't work, but there are two workaround, you can boot your computer 
with 7.4 kernel series (3.10.0-693.XXX) or you can run 2.11.0 client:
