Operating Systems Solaris Best way to copy 4Tb of data from one filesystem to another Post 302998064 by gandolf989 on Wednesday 24th of May 2017 02:28:14 PM

Personally I prefer rsync to cp. But for 4TB, it probably doesn't make enough of a difference. Are both volumes on the same server? Are you using a SAN? You might find that SAN snapshot and replication is the best way to move the data. But that depends on your storage system. You might want to provide more information on the type of disk storage that you use and check with your SAN vendor, if you use a SAN, to see what they think.

NAME
mkqdisk - Cluster Quorum Disk Utility WARNING
Use of this command can cause the cluster to malfunction. SYNOPSIS
mkqdisk [-?|-h] | [-L] | [-f label] [-c device -l label] [-d [-d ...]] DESCRIPTION
The mkqdisk command is used to create a new quorum disk or display existing quorum disks accessible from a given cluster node. OPTIONS
-c device -l label Initialize a new cluster quorum disk. This will destroy all data on the given device. If a cluster is currently using that device as a quorum disk, the entire cluster will malfunction. Do not run this on an active cluster when qdiskd is running. Only one device on the SAN should ever have the given label; using multiple different devices is currently not supported (it is expected a RAID array is used for quorum disk redundancy). The label can be any textual string up to 127 characters - and is therefore enough space to hold a UUID created with uuidgen(1). -f label Find the cluster quorum disk with the given label and display information about it. -L Display information on all accessible cluster quorum disks. -d Increase debugging level. Specify multiple times for more information. Currently, specifying more than twice has no effect. SEE ALSO
