probleme multipath
bonjour,
j'ai deux serveur SUN equipé par RHEL5.2 x86_64 :
SRV1 : 01FC mono + 01FC mono (qlogic)
SRV2 : 01FC dual (qlogic)

ça fonctionnait correctement et après une certaine période J'ai eu un problème lors du démarrage de SRV2.


udevd-event[3580]: wait_for_sysfs: waiting for '/sys/devices/pci0000:00/0000:00:0d.0/0000:04:00.0/host3/target3:0:0/3:0:0:0/ioerr_cnt' failed

Le fstab est correct sur SRV2:
/dev/dm-2 /data auto defaults 1 2
/dev/dm-3 /home auto defaults 1 2

Une fois SRV2 est démarrer, le /home est vide. Il faut que je fais mount /dev/dm-3 /home (ça se monte pas automatiquement)

Je trouve une différence entre SRV1 et SRV2 lorsque je fais : multipath -ll -v2

SRV1 :
mpath2 (3600a0b80004946b80000083b4a4a0137) dm-3 SUN,LCSM100_F
[size=305G][features=1 queue_if_no_path][hwhandler=1 rdac][rw]
\_ round-robin 0 [prio=100][active]
\_ 1:0:0:1 sdf 8:80 [active][ready]
\_ round-robin 0 [prio=0][enabled]
\_ 2:0:0:1 sdd 8:48 [active][ghost]
mpath1 (3600a0b8000493fb6000008674a4a0130) dm-2 SUN,LCSM100_F
[size=240G][features=1 queue_if_no_path][hwhandler=1 rdac][rw]
\_ round-robin 0 [prio=100][active]
\_ 2:0:0:0 sdc 8:32 [active][ready]
\_ round-robin 0 [prio=0][enabled]
\_ 1:0:0:0 sdb 8:16 [active][ghost]

SRV2 :
mpath17 (3600a0b80004946b80000083b4a4a0137) dm-2 SUN,LCSM100_F
[size=305G][features=1 queue_if_no_path][hwhandler=1 rdac][rw]
\_ round-robin 0 [prio=100][active]
\_ 3:0:0:1 sdd 8:48 [active][ready]
mpath16 (3600a0b8000493fb6000008674a4a0130) dm-3 SUN,LCSM100_F
[size=240G][features=1 queue_if_no_path][hwhandler=1 rdac][rw]
\_ round-robin 0 [prio=0][active]
\_ 3:0:0:0 sdc 8:32 [active][ghost]

c'est un problème de paths.



comment je peux résoudre ça.


Merci d'avance.

faxq

faxq(1) 						       mgetty+sendfax manual							   faxq(1)

NAME

       faxq - display fax jobs queued by faxspool(1)

SYNOPSIS

       faxq [-osa] [-v] [-r] [-P<job><prio>]

DESCRIPTION

       Display the fax queue set up by faxspool(1).

       faxq looks for all the jobs queued by faxspool(1) to /var/spool/fax/outgoing/*. For each job in the queue, faxq displays some status infor-
       mations about it. If no options are specified, one line per queued fax job is printed, displaying the job number, sender, number  of  pages
       and target fax number.

OPTIONS

       -v     Tells faxq to print a more verbose report for each job (multiple lines).

       -o     Show old jobs, already sent but still in the queue directory, too.

       -s     Show suspended jobs (stopped because of too many fatal errors during sending). You can restart those jobs with faxq -r

       -a     Show all jobs (active, old, suspended).

       -r     Restart  suspended  jobs.  Every	suspended  job	in the queue (that you have write permissions for) will be requeued.  Use faxrm to
	      delete jobs that you do not want to be sent!

       -P <job> <prio>
	      Change the priority of fax job <job> to <prio>. Example: "faxq -P F000247 3".

BUGS

       faxq doesn't handle time scheduling yet.
