NAME
sndiskmove - Xsan File System Disk Mover Utility
SYNOPSIS
sndiskmove [-fqv] [-s suffix] [-b bufMB] [-S file] <SourceVolume> <Des-
tinationVolume>
DESCRIPTION
sndiskmove is a utility for migrating the contents of a disk to a new
disk. This is accomplished by copying the data from the disk and rela-
beling the destination disk with the name of the source disk. The
source disk is also relabeled with its original name with a suffix
added (this is ".old" by default but this can be changed with the -s
option.
WARNING: Using this command incorrectly can cause loss of data. Please
ensure that you understand the procedures to safely execute this com-
mand completely. Also, this command is not supported for filesystem
disks that contain data, it must be used for Exclusive Metadata or
Journal disks only.
Attempting to run this command on a disk that is being used on an
actively running filesystem will cause data corruption. All referenc-
ing filesystems must be stopped and remain stopped during the process-
ing of this command.
If successful, the command will cause the local fsmpm process to rescan
the disks on the host where the command is executed. If there are any
FSMs configured on other hosts, it is critical to request a rescan of
the disks before reenabling the FSM on those servers by invoking
cvadmin -e 'disks refresh'
on those hosts.
OPTIONS
[-f] Forces the disk data to be moved without confirmation from the
user. WARNING: Use this flag with extreme caution!
[-q] Run in quiet mode. This disables the progress display.
[-v] Causes sndiskmove to be verbose.
[-s suffix]
Uses the supplied suffix to relabel the source disk.
[-b bufsizeMB]
Specifies the buffer size to use for the copying of disk data
(in megabytes). The default value is 4MB.
[-S file]
Writes status monitoring information in the supplied file. This
is used internally by Xsan and the format of this file may
change.
