I enabled local caching by performing the following-
xe sr-create name-label=LocalCache type=ext
device-config:device=/dev/disk/by-id/scsi-3600508e000000000112eee24192d3105-part4
xe host-enable-local-storage-caching
host=ccb23b66-8f51-4966-9491-e836c8203df6
sr-uuid=4c4e838d-5be9-361c-844f-f4d948a3902c
xe host-enable
In df, I can see:
/dev/mapper/XSLocalEXT--4c4e838d--5be9--361c--844f--f4d948a3902c-4c4e838d--5be9--361c--844f--f4d948a3902c
61616140 184272 58301912 1%
/var/run/sr-mount/4c4e838d-5be9-361c-844f-f4d948a3902c
For good measure, I turned off a VM I was running, and on it''s VDI
performed the following operation-
xe vdi-param-set uuid=82da6cd2-c65f-4b18-826d-e2f1abec195e allow-caching=true
This VM is on an LVM-over-ISCSI SR.
Now, when I start it up, I do not see the usage increase on the LocalCache
(/var/run/sr-mount/4c4e838d-5be9-361c-844f-f4d948a3902c) increase whatsoever.
How do I know if it''s even being used?
Yours,
Evan
