[Lustre-discuss] Running MGS and OSS on the same machine

2011-02-18 Thread Charland, Denis
Arya, I have the MGS, the MDT and the OST all on the same machine and everything works fine. It should not be a problem to have the MGS and the OST on the same machine. Are your MGS and MDT mounted when you execute mkfs.lustre for the OST? Denis Denis Charland, ing. | P. Eng. Administrateur d

Use the same NID as you would in any other case - 192.168.0.10@tcp0 in your example. It will work. You would do the same thing if for example you used one server for both MGS and MDS, but separate partitions - the MDT would have to be formatted with --mgsnode cliffw On Fri, Feb 18, 2011 at 7:10 A

[Lustre-discuss] lock callback timer expired

2011-02-18 Thread Joe Digilio
I've gotten hit with four "lock callback timer expired" events in the past week. The logs from one event are attached. I recently upgraded from 1.8.3 to 1.8.5. On 1.8.3 the error had only occurred once. Now, four times in a week. Looking through bugzilla, I thought it might be 23190 and 23963.

If I understand everything correctly page->private should contain either 0 or a pointer to kernel space. For reasons I can not currently comprehend sometimes the value is set to 2. llap_cast_private() then tries to access page->private->llap_magic, and naturally this leads to NULL pointer derefe

Hi Arya, if I remember well, Lustre uses 0@lo for the localhost address. Does using the other NID 192.168.0.10@tcp0 give any error message? Michael Am 18.02.2011 16:10, schrieb Arya Mazaheri: > Hi again, > I have planned to use one server as MGS and OSS simultaneously. But how > can I format t

Hi again, I have planned to use one server as MGS and OSS simultaneously. But how can I format the OSTs as lustre FS? for example, the line below tells the ost which it's mgsnode is at 192.168.0.10@tcp0: mkfs.lustre --fsname lustre --ost --mgsnode=192.168.0.10@tcp0 /dev/vg00/ost1 But, now mgsnode

Ww! Thanks for your suggestion. The only thing needed to do is to make the 'arcmsr.c' and 'arcmsr.h' and finally make the ram disk. Now everything is working smoothly... Thanks again... ;) On Fri, Feb 18, 2011 at 1:16 AM, Kevin Van Maren wrote: > Yep. All you have to do is rebuild the driv
