Well... Sometimes performance may suffer if you use one or two huge LUNs (more than 1TB) for your zpool. It depends on how busy is your application. If you don't see any "slowness", then you don't have to bother with optimizing that.
Hi
I have the following file system, that needs to be expanded to more 500Gb, so a total of 1Tb:
df -h /oradata1
Filesystem Size Used Available Capacity Mounted on
oradata1 587G 517G 69G 89% /oradata1
I am not familiar with zfs, I am more... (17 Replies)
Hi, I need to expand a ZFS volume from 500GB to 800GB. I'd like to ask your help to confirm the following procedure:
Can I do it on the fly without bothering the users working on this volume?
Thank you in advance! (6 Replies)
I have a 146Gb drive and want to grow the size from 12G to the max available left. I think 20G is being used so I want to max out from 12 G to 126G. Is this possible? Can you help with the command.

Greetings,
I am running HP-UX 10.2 and /usr is out of disk space already. I installed IE 5.0 for UNIX on my machine under /usr and browsed the Internet for a while and presto no more disk space.
I have plenty of hard disk space on my computer so would like to expand the size of the volume. The... (5 Replies)
Hi,
We have 12x1TB SATA disks in our array and I need to create 10TB volume. I defined new storage profile on array and when I tried to add volume, I faced with ~2TB limit for new volumes. I didn't find how to set another limit on my storage profile. Is there is a way to configure one large... (3 Replies)

amzfs-sendrecv - Amanda script to create zfs sendrecv
DESCRIPTION
amzfs-sendrecv is an Amanda application implementing the Application API. It should not be run by users directly. It create a zfs snapshot
of the filesystem and backup the snapshot with 'zfs send'. Snapshot are kept after the backup is done, this increase the disk space use on
the client but it is neccesary to be able do to incremental backup. If you want only full backup, you can disable this feature by setting
the KEEP-SNAPSHOT property to 'NO'. Only the restoration of the complete backup is allowed, it is impossible to restore a single file.
The application is run as the amanda user, it must have many zfs priviledge:
zfs allow -ldu AMANDA_USER mount,create,rename,snapshot,destroy,send,receive FILESYSTEM
Some system doesn't have "zfs allow", but you can give the Amanda backup user the rights to manipulate ZFS filesystems by using the
following command:
usermod -P "ZFS File System Management,ZFS Storage Management" AMANDA_USER
This will require that your run zfs under pfexec, set the PFEXEC property to YES.
The format of the diskdevice in the disklist (DLE) must be one of:
Desciption Example
-----------------
Mountpoint /data
ZFS pool name datapool
ZFS filesystem datapool/database
ZFS logical volume datapool/dbvol
The filesystem doesn't need to be mounted.
PROPERTIES
This section lists the properties that control amzfs-sendrecv's functionality. See amanda-applications(7) for information on the
Application API, application configuration.
DF-PATH
Path to the 'df' binary, search in $PATH by default.
KEEP-SNAPSHOT
If "YES" (the default), snapshot are kept after the backup, if set to "NO" then snapshot are no kept and incremental backup will fail.
ZFS-PATH
Path to the 'zfs' binary, search in $PATH by default.
PFEXEC-PATH
Path to the 'pfexec' binary, search in $PATH by default.
PFEXEC
If "NO" (the default), pfexec is not used, if set to "YES" then pfexec is used.
EXAMPLE
In this example, a dumptype is defined to use amzfs-sendrecv application to backup a zfs filesystem.
define application-tool amzfs_sendrecv {
comment "amzfs-sendrecv"
plugin "amzfs-sendrecv"
#property "DF-PATH" "/usr/sbin/df"
#property "KEEP-SNAPSHOT" "YES"
#property "ZFS-PATH" "/usr/sbin/zfs"
#property "PFEXEC-PATH" "/usr/sbin/pfexec"
#property "PFEXEC" "NO"
}
define dumptype user-zfs-sendrecv {
program "APPLICATAION"
application "amzfs_sendrecv"
}
