Functions ¶
func AllBlockDevs ¶
func AllBlockDevs() []string
Return a path for each non-virtual block device. Unlike Devices(), include partitions.
func BFiltNotRecovery ¶
func DFiltOnlyParts ¶
func DFiltOnlyUsb ¶
func DFiltOnlyUsbParts ¶
func FilterBlockDevs ¶
func FilterBlockDevs(filter DevIncludeFn) []string
like AllBlockDevs, but uses a filter function to limit the results
func PartParent ¶
PartParent returns the parent block device for the given partition. Does not check if dev is actually a partition.
func ReadModel ¶
given a dev like '/dev/sda', find device model string for sata, 'model' file includes vendor as well
func ReadVendor ¶
for sata, always returns ATA for scsi, ??? for usb, returns actual vendor
func SizeToleranceMatch ¶
SizeToleranceMatch returns true if actual value is within tolerance of desired value. Tolerance is expressed as an integer 1-100, representing a percent.
Types ¶
type BlkIncludeFn ¶
a function that returns false if given bi should be filtered out
type BlkInfo ¶
type BlkInfo struct {
FsType FsType
UUID string
Partition bool
PartUUID string
Label string
Usage string
Device string
}
func GetFilesystems ¶
func GetFilesystems(blkfilter BlkIncludeFn, devfilter DevIncludeFn) []BlkInfo
return a BlkInfo for each blockdevice containing a filesystem we recognize
type DevIncludeFn ¶
A function that returns true if the entry is to be kept. relpath is relative to dir, which is likely /sys/class/block.
