As long as there are no overlapping areas, that doesn't matter.
If your SSD is a $500k house, these gaps sum up to less than two tenth of a cent...
Hahaha jlliagre, nice analogy..
Thank for your reply. I am just wondering why are these sectors distributed in such way and how they sums up.
Last question i hope you don't mind, since these are 4k disks, is there any reason why ZFS are aligning them with start sector 256 ? instead of the default 40 ?
Code:
40 = 40 * 512 = 20480bytes
20480bytes/4096=5 x 4k sector - which is in multiples of 4k and should be fine.

Here is a script for automatic labeling of previously unlabeled disks.
Other methods exist (format -f cmd_file), but I like this because it's all in one place.

Is there a way to determine the number of available spare sectors on a disk ? as it may be useful for notifying a user to take a backup of the disk before it runs into a medium error. (6 Replies)

efi_rmdir
efi_rmdir(1M)efi_rmdir(1M)NAME
efi_rmdir - remove an EFI directory
SYNOPSIS
devicefile] directory
DESCRIPTION
removes an EFI directory
The EFI file system is based on the FAT file system and used by the Itanium-based system BIOS to locate an HP-UX bootloader. See efi(4).
devicefile should be the device file for the EFI volume.
If directory is not a directory or the directory is not empty, prints a diagnostic message and returns without removing the file; use
efi_rm(1M) to remove EFI files. directory should be relative to root of the EFI volume specified by devicefile, not to an HP-UX file sys-
tem.
Options
recognizes the following option:
devicefile is the device special file of the EFI file system from which the directory is to be removed. Without the option, uses the
device file specified in the environment variable if it is defined. The option overrides the environment variable.
RETURN VALUE
returns exit code 0 if the directory is removed successfully. Otherwise it prints a diagnostic message and returns nonzero.
0 Successful completion.
>0 Error condition occurred.
EXAMPLES
