Troubleshooting VMFS issues
VMFS is a high performance distributed filesystem. VMFS version 5 supports up to 60 TB of file size. Here are some important guidelines you should consider when working with VMFS volumes:
- If you are not able to store files from 2 TB to 60 TB, make sure the partition table is using GPT instead of MBR. You can use
partedUtil to view the partitioning.
- The free space threshold value of a VMFS as suggested by VMware is 200 MB, and once 100 MB space is left, you will start having problems.
