Error in increase or modify the groupsize and groupmod parameters for eos space define

Hi,

We have face an error i.e. “error: scheduling group default.3 is full. error: no group available for file system”.

Then we have try to increasing the value of groupsize and groupmod of scheduling group. But, it’s gives errors below:-

=========================================

[root@eos-slave ~]# eos space define default groupmod=18
terminate called after throwing an instance of ‘std::invalid_argument’
what(): stoi
Aborted (core dumped)
[root@eos-slave ~]# eos space define default groupsize=9
terminate called after throwing an instance of ‘std::invalid_argument’
what(): stoi
Aborted (core dumped)
[root@eos-slave ~]#

=====================================

Current default value of groupsize and groupmod for eos space are -

groupmod := 24
groupsize := 0

(EOS version is 5.3.24)

So, How to change groupsize and groupmod ?

Cheers,

Prasun

Hi Prasun,

Before increasing the group size or mode I would check the output of the eos group ls and eos group ls –io command. This can also happen if some of your file systems are not online/available. So, double check that all your file systems are fine:
eos fs ls
The command to change the group size mod is:
eos space define default 0 18
have a look at the eos space -h output and you will see the correct syntax.

Cheers,

================================

as per your suggestion , we had increase the groupsize and it working well.

We has 16 groups and each group contains 8 nos. of disks.

So, accordingly, we has increase groupsize 0 to 8.

Thank You very much Elvin.

Cheers
