Full Discussion: Exporting physical disk to ldom or ZFS volume
Operating Systems Solaris Exporting physical disk to ldom or ZFS volume Post 303016066 by psychocandy on Thursday 19th of April 2018 05:16:26 AM

Exporting physical disk to ldom or ZFS volume
Generally, this is what we do:-
  1. On primary, export 2 LUNs (add-vdsdev).
  2. On primary, assign these disks to the ldom in question (add-vdisk).
  3. On ldom, created mirrored zpool from these two disks.

On one server (which is older) we have:-
  1. On primary, create mirrored zpool from the two LUNs.
  2. On primary, assign this zfs disk to the ldom in question (add-vdisk).
  3. On ldom, create single disk zpool from this.

On this one server we're getting performance issues. I've heard that doing it this way (i.e. mirrored zfs on primary and exporting this) is not the best way to do it and will create an overhead?

Is this true? Or doesn't it make any difference?

zdb

zdb(1M) 						  System Administration Commands						   zdb(1M)

NAME

       zdb - ZFS debugger

SYNOPSIS

       zdb pool

DESCRIPTION

       The  zdb command is used by support engineers to diagnose failures and gather statistics. Since the ZFS file system is always consistent on
       disk and is self-repairing, zdb should only be run under the direction by a support engineer.

       If no arguments are specified, zdb, performs basic consistency checks on  the  pool  and  associated  datasets,	and  report  any  problems
       detected.

       Any options supported by this command are internal to Sun and subject to change at any time.

EXIT STATUS

       The following exit values are returned:

       0    The pool is consistent.

       1    An error was detected.

       2    Invalid command line options were specified.
