Hello,
I have a trouble mounting my lustre clients in MDS/MGS high availability. This is my scenario: MDS1: primary MDS/MGS MDS2: backup MDS/MGS OSS1 OSS2 ... OSS8 I mount my clients: mount -t lustre mds1@o2ib:mds2@o2ib:/fs /mnt/fs 1) When both MDS are OK I can mount without problems 2) If the MDS1 is down and my clients have lustre mounted, they use MDS2 without problems 3) If the MDS1 is down and I try to mount a new client, It can’t mount lustre with the next error: arg[0] = /sbin/mount.lustre arg[1] = -v arg[2] = -o arg[3] = rw arg[4] = 192.168.8.9@o2ib:192.168.8.9@o2ib:/fs arg[5] = /mnt/fs source = 192.168.8.9@o2ib:192.168.8.9@o2ib:/fs (192.168.8.9@o2ib:192.168.8.9@o2ib:/fs), target = /mnt/fs options = rw mounting device 192.168.8.9@o2ib:192.168.8.9@o2ib:/fs at /mnt/fs, flags=0x1000000 options=device=192.168.8.9@o2ib:192.168.8.9@o2ib:/fs mount.lustre: mount 192.168.8.9@o2ib:192.168.8.9@o2ib:/fs at /mnt/fs failed: Input/output error retries left: 0 mount.lustre: mount 192.168.8.9@o2ib:192.168.8.9@o2ib:/fs at /mnt/fs failed: Input/output error Is the MGS running? I suspect that the new client try to mount using MDS1, but if is down, they don’t try to mount using the next MDS. Any suggestion? ----------------------------------------------------------------------------- Alfonso Pardo Díaz Researcher / System Administrator CETA-Ciemat C/Sola Nº1. 10200 - TRUJILLO, SPAIN Teléfono. +34 927659317 (ext. 214) FAX +34 927323237 [cid:A9E2233C-3F99-40A6-B088-531EA585AD26@ceta-ciemat.es] ---------------------------- Confidencialidad: Este mensaje y sus ficheros adjuntos se dirige exclusivamente a su destinatario y puede contener informaci�n privilegiada o confidencial.
