Hi, I would like to mount multipath volumes with /etc/fstab. I have storage attached to my Debian server with redundant paths. There are 3 volumes and 2 possible paths to each.
Here goes the list displayed by multipath -ll: # multipath -ll 3600c0ff00010b3e0a1e32d4d03000000 dm-2 HP,MSA2312fc size=1.4T features='1 queue_if_no_path' hwhandler='0' wp=rw |-+- policy='round-robin 0' prio=50 status=active | `- 6:0:2:3 sdd 8:48 active ready running `-+- policy='round-robin 0' prio=10 status=enabled `- 6:0:3:3 sdg 8:96 active ready running 3600c0ff00010b3e0a1e32d4d01000000 dm-0 HP,MSA2312fc size=1.4T features='1 queue_if_no_path' hwhandler='0' wp=rw |-+- policy='round-robin 0' prio=50 status=active | `- 6:0:2:1 sdb 8:16 active ready running `-+- policy='round-robin 0' prio=10 status=enabled `- 6:0:3:1 sde 8:64 active ready running 3600c0ff00010b3e0a1e32d4d02000000 dm-1 HP,MSA2312fc size=1.4T features='1 queue_if_no_path' hwhandler='0' wp=rw |-+- policy='round-robin 0' prio=50 status=active | `- 6:0:2:2 sdc 8:32 active ready running `-+- policy='round-robin 0' prio=10 status=enabled `- 6:0:3:2 sdf 8:80 active ready running Disks by path: # ls -l /dev/disk/by-path/ total 0 lrwxrwxrwx 1 root root 9 Mar 24 15:04 pci-0000:00:1f.1-scsi-0:0:0:0 -> ../../sr0 lrwxrwxrwx 1 root root 9 Mar 24 15:04 pci-0000:02:0e.0-scsi-0:2:0:0 -> ../../sda lrwxrwxrwx 1 root root 10 Mar 24 15:04 pci-0000:02:0e.0-scsi-0:2:0:0-part1 -> ../../sda1 lrwxrwxrwx 1 root root 10 Mar 24 15:04 pci-0000:02:0e.0-scsi-0:2:0:0-part2 -> ../../sda2 lrwxrwxrwx 1 root root 10 Mar 24 15:04 pci-0000:02:0e.0-scsi-0:2:0:0-part3 -> ../../sda3 lrwxrwxrwx 1 root root 9 Mar 24 15:04 pci-0000:0c:06.0-fc-0x217000c0ff10a22c:0x0001000000000000 -> ../../sdb lrwxrwxrwx 1 root root 10 Mar 24 15:04 pci-0000:0c:06.0-fc-0x217000c0ff10a22c:0x0001000000000000-part1 -> ../../sdb1 lrwxrwxrwx 1 root root 9 Mar 24 15:04 pci-0000:0c:06.0-fc-0x217000c0ff10a22c:0x0002000000000000 -> ../../sdc lrwxrwxrwx 1 root root 10 Mar 24 15:04 pci-0000:0c:06.0-fc-0x217000c0ff10a22c:0x0002000000000000-part1 -> ../../sdc1 lrwxrwxrwx 1 root root 9 Mar 24 15:04 pci-0000:0c:06.0-fc-0x217000c0ff10a22c:0x0003000000000000 -> ../../sdd lrwxrwxrwx 1 root root 10 Mar 24 15:04 pci-0000:0c:06.0-fc-0x217000c0ff10a22c:0x0003000000000000-part1 -> ../../sdd1 lrwxrwxrwx 1 root root 9 Mar 24 15:04 pci-0000:0c:06.0-fc-0x257000c0ff10a22c:0x0001000000000000 -> ../../sde lrwxrwxrwx 1 root root 10 Mar 24 15:04 pci-0000:0c:06.0-fc-0x257000c0ff10a22c:0x0001000000000000-part1 -> ../../sde1 lrwxrwxrwx 1 root root 9 Mar 24 15:04 pci-0000:0c:06.0-fc-0x257000c0ff10a22c:0x0002000000000000 -> ../../sdf lrwxrwxrwx 1 root root 10 Mar 24 15:04 pci-0000:0c:06.0-fc-0x257000c0ff10a22c:0x0002000000000000-part1 -> ../../sdf1 lrwxrwxrwx 1 root root 9 Mar 24 15:04 pci-0000:0c:06.0-fc-0x257000c0ff10a22c:0x0003000000000000 -> ../../sdg lrwxrwxrwx 1 root root 10 Mar 24 15:04 pci-0000:0c:06.0-fc-0x257000c0ff10a22c:0x0003000000000000-part1 -> ../../sdg1 Disks by UUID: lrwxrwxrwx 1 root root 10 Mar 24 15:04 1ec887b9-6d38-4314-b472-9ca797c81715 -> ../../sdf1 lrwxrwxrwx 1 root root 10 Mar 24 15:04 7fa1c2b9-bc1d-456a-aedd-67f00eb99bf6 -> ../../sda2 lrwxrwxrwx 1 root root 10 Mar 24 15:04 f1325167-0ed8-4a5e-8719-6e2bb8e22cbd -> ../../sda1 I actually need to mount sdf1 partition through /etc/fstab. I tried both ways: UUID=1ec887b9-6d38-4314-b472-9ca797c81715 /backup ext4 errors=remount-ro 0 2 /dev/disk/by-id/dm-uuid-part1-mpath-3600c0ff00010b3e0a1e32d4d02000000 /backup ext4 errors=continue 0 2 but neither worked. When booting there is following error message and the system goes into maintenance (even though there is "errors=continue" in /etc/fstab): device-mapper: table: multipath: error getting device done Finally I took a work around method and I mount it by an entry in /etc/rc.local: mount /dev/mapper/3600c0ff00010b3e0a1e32d4d02000000-part1 /backup which actually works but I would rather do it by /etc/fstab, tho. Could you please tell me why device-mapper can't "get device done"? Best regards, Mike -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
