blockdev_getbsz

Description:

[ Version ( since = "1.9.3" ) ]
public int32 blockdev_getbsz (string device) throws Error

get blocksize of block device

This returns the block size of a device.

Note: this is different from both *size in blocks* and *filesystem block size*. Also this setting is not really used by anything. You should probably not use it for anything. Filesystems have their own idea about what block size to choose.

This uses the blockdev(8) command.

Parameters:

this	A GuestfsSession object

Returns:

the returned value, or -1 on error
