Hi Folks
I am confused about a ZVOL i created in TRUE NAS. When i look at the properties of the ZVOL i see the following.
` PROPERTY VALUE SOURCE
used 115G -
available 16.0T -
referenced 21.3G -
compressratio 1.33x -
reservation none default
volsize 100G local
volblocksize 32K -
checksum on default
compression lz4 inherited from VDEV1
refreservation 115G local
usedbysnapshots 0B -
usedbydataset 21.3G -
usedbychildren 0B -
usedbyrefreservation 93.7G -
`
My queries
- How is it that used value at 115G is greater that vol size of 100G
- How is Available 16T when ZVOL size is 100G
- What is usedbyrefreservation and how do i reduce the size of it.
- How do i find out what is the actual usage so that i know when to step in and increase the ZVOL Size
