Filesystem creation examples
The following command creates filesystems on array 3. Since no mount points or sizes were specified,
the command will create two filesystems, each of 29 TB and mount them on /mnt/exds_3_1 and
/mnt/exds_3_2.
# exdsmgr create filesystem array=3
The following command creates a single filesystem using all available storage in an array:
# exdsmgr create filesystem array=4 size=58 mount=/usr/data1
The following creates three filesystems of different sizes on an array:
# exdsmgr create filesystem array=5 size=14,14,29 \
mount_points=/mnt/a,/mnt/b,/mnt/c
This could also have been done as two separate commands:
# exdsmgr create filesystem array=5 size=14,14 \
mount_points=/mnt/a,/mnt/b
# exdsmgr create filesystem array=5 size=29 mount_points=/mnt/c
When creating a filesystem, you can optionally assign a label to the filesystem. This label can be
useful if you need to delete a filesystem that is only partially created. If you do not specify a label, a
default label is constructed. The guidelines for creating a label are as follows:
• Characters A-Z, a-z, 0-9, underscore (_) and dash (-) are allowed.
• Do not use blank spaces.
• Maximum length allowed is 12 characters.
The following example shows the data1 and data2 labels being assigned when creating a filesystem:
# exdsmgr create filesystem array=3 label=data1,data2
Recovering from a filesystem creation failure
If the exdsmgr create filesystem command fails during the creation process, the filesystem is
not fully functional. Delete the filesystem using the exdsmgr delete filesystem command and
start again. Most filesystem-related commands use the device name (for example, psv5) to identify
the filesystem. However, this is only useful if the system had finished creating a dynamic volume. If
the create filesystem command fails before the dynamic volume is created, you must use the
filesystem name. Optionally, you can specify the name when you create the filesystem. If you did not
specify a name, use the exdsmgr show filesystem command to find the filesystem name.
