similar to: How To change server recovery timeout

This morning I''ve had both my infiniband and tcp lustre clients hiccup. They are evicted from the server presumably as a result of their high load and consequent timeouts. My question is- why don''t the clients re-connect. The infiniband and tcp clients both give the following message when I type "df" - Cannot send after transport endpoint shutdown (-108). I''ve

on our cluster that has been running lustre for about 1 month. I have 1 MDT/MGS and 1 OSS with 2 OST''s. Our cluster uses all Gige and has about 608 nodes 1854 cores. We have allot of jobs that die, and/or go into high IO wait, strace shows processes stuck in fstat(). The big problem is (i think) I would like some feedback on it that of these 608 nodes 209 of them have in dmesg

What should I do ? How to configure? thanks! swin -------------- next part

Hello, ? ?I wonder if it is possible to dynamically enable/disable samba 3 shares.? Here is my problem.? On a remote server I have 4 removable hard drives, large capacity. I am not using any RAID/JBOD, so each drive is mounted individually (like /mnt/DISK1, /mnt/DISK2 etc) and each drive is individually shared, something like: [STORAGE01] path = /mnt/DISK1 Guest OK = false ... [STORAGE02]

Hi, We have seen a huge performance drop in 1.6.3, due to the checksum being enabled by default. I looked at the algorithm being used, and it is actually a CRC32, which is a very strong algorithm for detecting all sorts of problems, such as single bit errors, swapped bytes, and missing bytes. I''ve been experimenting with using a simple XOR algorithm. I''ve been able to recover

Hi all, we use SLES 11 and Lustre 1.8.1.1 + patches and like convert a lustre FS using external journals to one with async journals enabled. Question is whether the procedure: umount <filesystem> on all clients umount <osts> on all OSSes e2fsck <ost-device> on all OSSes for all all OSTs tune2fs -O ^has_journal <ost-device> on all

Hi There, I've been using Samba for years and years but I've hit a problem that I just don't understand. We have a storage server that's been running nicely for 18 months. It does NFS for virtual machines and SMB for Windows storage. The machine is domain joined and seems in good order. Recently (and coincidently) we made some changes to our domain controllers and since then
