I'm using a file for an iscsi block device. I made it using fallocate (
) and with the "iscsitarget" package.
fallocate -l 200g /mnt/iscsi/lun0.img
Uisng Windows SBS 2011, I connected(iscsi initiator tool from Windows admin tools) to it and formatted it NTFS, and started using it as a local drive. So far, so good.
But I'd like to append another 300G to it , for a total of 500G. I think this command will work ( from the man page ):
The thing that I'm uncertain is the offset( -o ), I'm not sure if its value should match the size, or should be 1 unit greater than the size of the existing .img file.
fallocate -o 200g -l 300g /mnt/iscsi/lun0.img
Does anyone with experience using fallocate care to chime in? I'm new to iscstarget and fallocate, so I'm not yet confident in using them.
