Red Hat Summit5.6. DM Multipath overrides of the device timeout (dépassement du délai d'attente de l'appareil)
L'option recovery_tmo sysfs contrôle le délai d'attente pour un périphérique iSCSI particulier. Les options suivantes remplacent globalement les valeurs de recovery_tmo:
-
L'option de configuration
replacement_timeoutremplace globalement la valeurrecovery_tmopour tous les périphériques iSCSI. Pour tous les dispositifs iSCSI gérés par DM Multipath, l'option
fast_io_fail_tmode DM Multipath remplace globalement la valeurrecovery_tmo.L'option
fast_io_fail_tmode DM Multipath remplace également l'optionfast_io_fail_tmodes périphériques Fibre Channel.
L'option DM Multipath fast_io_fail_tmo est prioritaire sur replacement_timeout. Red Hat ne recommande pas l'utilisation de replacement_timeout pour remplacer recovery_tmo dans les périphériques gérés par DM Multipath car DM Multipath réinitialise toujours recovery_tmo, lorsque le service multipathd est rechargé.
