The iscsi timeout defaults to 120 sec. This 2 minute delay would appear to be expected -- I'm inclined to close this NOTABUG but will defer to Ben. Mike is correct. Running multipath -ll calls the path checker. You are using the readsector checker, which tries to read the first sector of the device. This won't return until iscsi times out. If you just want a listing of you multipath devices, just run # multipath -l This won't run the path checker. For more information on how to avoid this, read section 8.1 (iSCSI settings for dm-multipath) in: /usr/share/doc/iscsi-initiator-utils-<version>/README |
