Hi Atmane,
>> I can not find the free space
Based on your output below, your setup currently has two recovery groups
BB1RGL and BB1RGR.
Issue "mmlsrecoverygroup BB1RGL -L" and "mmlsrecoverygroup BB1RGR -L" to
obtain free space in each DA.
Based on your "mmlsrecoverygroup BB1RGL -L" output below, BB1RGL "DA1" has
12GiB and "DA2" has 4GiB free space. The metadataOnly and dataOnly
vdisk/NSD are created from DA1 and DA2.

DA2 no 6 58 2,31 2 4096 MiB 14

In addition, you may use "mmlsnsd" to obtain mapping of file-system to
vdisk/NSD + use "mmdf <fs>" command to query user or available capacity on
a GPFS file system.
Hope this helps,

You can check the recovery groups to see if there is any remaining space.
I don't have access to my test system to confirm the syntax however if
memory serves.
Run mmlsrecoverygroup to get a list of all the recovery groups then:
mmlsrecoverygroup <YOURRECOVERYGROUP> -L
This will list all your declustered arrays and their free space.
Their might be another method, however this way has always worked well for
me.

Dear all,
My name is Khiredine Atmane and I am a HPC system administrator at the
National Office of Meteorology Algeria . We have a GSS24 running
gss2.5.10.3<http://2.5.10.3>-3b and gpfs-4.2.0.3<http://4.2.0.3>.
GSS configuration: 4 enclosures, 6 SSDs, 1 empty slots, 239 disks total, 0
NVRAM partitions
disks = 3Tb
SSD = 200 Gb
df -h
Filesystem Size Used Avail Use% Mounted on
/dev/gpfs1 49T 18T 31T 38% /gpfs1

/dev/gpfs3 25T 4.9T 20T 21% /gpfs3
/dev/gpfs4 11T 133M 11T 1% /gpfs4
/dev/gpfs5 323T 34T 290T 11% /gpfs5
Total Is 461 To
I think we have more space
Could anyone make recommendation to troubleshoot find how many free space
in GSS ?
How to find the available space ?
Thank you!
Atmane
