Install cluster in RH7 VM - minimal_disk_space error

[ch.cheung]

I install memsql into Linux VM RH7 with version 7.3.7.

I run into problem in creating database - It will complaint

Available disk space is below the value of ‘minimal_disk_space’ global variable (100 MB). This query cannot be executed.

I am sure that my space on /var/lib/memsql is more than enough

Filesystem Size Used Avail Use% Mounted on
/dev/mapper/rootvg-memsqlvol 5.0G 141M 4.9G 3% /var/lib/memsql

select @@datadir ;
/var/lib/memsql/6c00b88b-122f-49b0-86d9-c0d361791b45/data

Tracelog show the below
1801202593 2021-04-20 16:54:32.356 ERROR: Thread 114996: CreateFileAndAllocateSpace: Failed to allocate space for file logs/nex_19_staging: 28 (No space left on device).

Does anyone run into similar issue?

This post says to check the paths for tracelogs and plan cache as well:

`CREATE DATABASE` failed

Do those have enough space?

[ch.cheung]

All those 3 paths are under /var/lib/memsql. Should have more than enough space.

As this is a VM, what type of disk allocation are you using?

Thin provisioning might be causing this problem.

[ch.cheung]

This is thick provision disk. I am sure datastore level has more than enough space.
