RAM disk is full (2001550)

  • 49 Ratings



One of the RAM disk that make up the ESXi host root file system might reach its resource pool limit as a result of a software failure or an accidental use of an incorrect path.


When an administrator manually copies files to the host and accidentally uses an incorrect path (that is, one outside /vmfs/volumes), this error message appears:

The ramdisk 'root' is full. As a result, the file /testfile could not be written.

Also, in the /var/log/vmkernel.log file, you may see the error:

VisorFSRam: 233: Cannot extend visorfs file /var/lib/vmware/hostd/journal/ because its ramdisk (root) is full.


Files on the affected RAM disk can no longer be extended.

Various administrative actions depend on the ability to write files to various parts of the root file system and may fail if a RAM disk is full.
