The customer can use the new space by creating new vdisk sets from the available space. When
the vdisk sets are added to the existing le system (if needed), the restripe operation can be run.
For more information, see IBM Spectrum Scale: Administration Guide. When you are adding a vdisk
set to a le system, the default TRIM setting is "no" irrespective of the TRIM settings of the existing
vdisk sets. Issue the mmvdisk filesystem add command with the --trim {auto|no} option
to select TRIM settings when you are adding a vdisk set to a le system. For more information,
see Enable, disable, extend, and view TRIM settings on an existing declustered array and le system
in the Managing TRIM support for storage space reclamation chapter in IBM Spectrum Scale RAID:
Administration Guide.
Formatting drives example
Drives must be formatted as 4 KiB + 0 B before you add them to a recovery group. Ensure that the drives
are not part of an existing recovery group. If you format a drive that is a part of the existing recovery group
will lead to loss of data.
1. Create a list of drives as DONOTFORMAT.list that are part of an existing recovery group.
2. Create a list of drives as FORMAT.list that are NOT part of an existing recovery group and need to be
formatted.
3. Ensure that drives in the FORMAT.list list are NOT in the DONOTFORMAT.list list.
4. Format drives in the FORMAT.list list.
5. Verify that all drives are formatted correctly.
Example
1. Create a list of drives that are part of a recovery group.
# tspreparedisk -s | grep pdisk | awk '{print $2}' | sort > /tmp/DONOTFORMAT.list
Check the listed drives.
# cat /tmp/DONOTFORMAT.list
A sample output is as follows:
/dev/nvme10n1
/dev/nvme11n1
/dev/nvme18n1
/dev/nvme19n1
/dev/nvme20n1
/dev/nvme21n1
/dev/nvme22n1
/dev/nvme23n1
/dev/nvme6n1
/dev/nvme7n1
/dev/nvme8n1
/dev/nvme9n1
2. Create a list of drives that are not part of a recovery group and did not format as 4 KiB + 0 B.
# nvme list | grep Flash | awk '{print $1}' | grep -v -f /tmp/DONOTFORMAT.list | grep -v
'4 KiB + 0 B' | sort > /tmp/FORMAT.list
Check the listed drives.
# cat /tmp/FORMAT.list
A sample output is as follows:
