[zfs-discuss] ZFS: How to increase the size of one of the mount points
I have a cu that would like to increase a mount point with his
zpool....Cu explains below.
I need to increase the size of one of the mount points, i.e. /d01. I
need the procedure to do this while on line. attached is the information
I have on my server
as you will see I have the command "zpool status" executed and also a
df
-h. I need to increase the size of /d01
I need the step by step command to do this
sr1-ubur-06 97 =>more dfh

[zfs-discuss] ZFS: How to increase the size of one of the mount points
The user has set an explicit quota on the filesystems (50G on d[1-3], 175G on d[4-5]). You can increase the quota using ''zfs set quota'' or eliminate it alltogether using ''zfs inherit quota''. See zfs(1M) for more information. Incidentally, ''zfs list'' is a much easier way to view this information over a combination of zpool and df. - Eric On Mon, Jun 18, 2007 at 03:20:20PM -0400, Kenneth.Boyd at sun.com wrote:> I have a cu that would like to increase a mount point with his > zpool....Cu explains below. > > I need to increase the size of one of the mount points, i.e. /d01.
