@ -38,9 +38,33 @@ The `crio` table supports the following options:
**storage_driver**=""
CRIO storage driver (default is "overlay")
Note:
**overlay** and **overlay2** are the same driver
**storage_option**=[]
CRIO storage driver option list (no default)
Values:
"STORAGE_DRIVER.imagestore=/PATH",
Paths to additional container image stores. These are read/only and are usually stored on remote network shares, based on overlay storage format.
storage_option=[ "overlay.imagestore=/mnt/overlay", ]
"STORAGE_DRIVER.size=SIZE"
Maximum size of a container image. Default is 10GB. The size flag sets quota on the size of container images.
storage_option=[ "overlay.size=1G", ]
Note: Not all drivers support all options.
Note: In order to use the **size** option for quota on *overlay* storage you must use the *xfs* file system. The mount point that the *overlay* file system must be setup with the *pquota* flag at mount time. If you are setting up / to be used with quota, you have to modify the linux boot line in /etc/grubq2.conf and add the rootflags=pquota flag.
Example:
linux16 /vmlinuz-4.12.13-300.fc26.x86_64 root=/dev/mapper/fedora-root ro rd.lvm.lv=fedora/root rd.lvm.lv=fedora/swap rhgb quiet LANG=en_US.UTF-8 rootflags=pquota
