[Bug 547091] Re: 10.04 beta 1 mountall fails to mount iSCSI volume at boot

Tue Jan 3 23:13:12 UTC 2017

The issue is that the mountall command processes all entries in
/etc/fstab, including -netdev.  If the only requirement is for the
network to be up, such as NFS or CIFS then it works correctly.  But for
iscsi the device is "remote" but requires that open-iscsi init.d script
be run first.  Thus the mountall fails because the hard device doesn't
exist yet.

The work around that I'm currently using is to set all the iscsi devices
in /etc/fstab to "noauto".  Then the open-iscsi start script is modified
so the "mount -a -O _netdev" command is replaced with "mount
/mount_point"  We can't use the -a option because the noauto causes -a
to fail.  We can't use _netdev because the mountall fails.

Title:
  10.04 beta 1 mountall fails to mount iSCSI volume at boot

Status in open-iscsi package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: mountall

  Description: Ubuntu lucid (development branch)
  Release: 10.04
  Relevant Packages:
  - mountall 2.8
  - mount 2.17.2-0ubuntu1
  - open-iscsi 2.0.871-0ubuntu4
  - open-iscsi-utils 2.0.871-0ubuntu4

  After installing open-iscsi I can discover and login to a target. This
  creates relevant entries in /etc/iscsi/nodes. In iscsid.conf
  "node.startup" is set to "automatic". My /etc/fstab contains an entry
  to mount the iSCSI volume at boot:

  UUID=<disk_uid> /var/lib/eucalyptus/instances ext3 rw,relatime,_netdev
  0 0

  UUID is determined by using "fdisk -l" and then checking the relevant
  drive entry under /dev/disk/by-uuid. Manual mount works, so it is
  expected that it should work on boot.

  Expected behavior:
  The iSCSI volume is mounted according to its fstab entry at boot

  Actual behavior:
  Boot fails and hangs with the following message:

  mount: special device UUID=<disk_uid_from_fstab> does not exist
  mountall: mount /var/lib/eucalyptus/instances [900] terminated with status 32
  mountall: Filesystem could not be mounted: /var/lib/eucalyptus/instances
  mountall:mountall.c:2726: Not reached assertion failed in boredom_timeout
  General error mounting filesystems.
  A maintenance shell will now be started.

  After dropping to the maintenance shell and issuing "mount -a -O
  _netdev" the iSCSI volume mounts fine. Also, dmesg shows that iSCSI is
  started at boot and the volume is detected and attached and "fdisk -l"
  confirms this.
