Subject: gdisk-created Bios Boot Partition created with NO fs, reports fs TYPE=ext4. Bug/why?
Date: Sun, 15 Feb 2015 10:38:56 -0800 [thread overview]
Message-ID: <1424025536.1061731.227795501.40064DE9@webmail.messagingengine.com> (raw)
I'm not entirely sure this is the right list for this question, but it IS ext4 'involved'. So ...
I create a GPT Bios Boot Partition on a clean disk
sgdisk -z /dev/sdc
sgdisk -o /dev/sdc
sgdisk -n 1:2048:+1M -t 1:ef02 -c 1:"BIOS Boot" /dev/sdc
IIUC, at this point, the partition should exist with NO filesystem.
But, if I check with blkid
blkid /dev/sdc1
/dev/sdc1: LABEL="RAID_BOOT" UUID="8a828baa-f315-4456-88d2-ff14849eb705" TYPE="ext4" PARTLABEL="BIOS Boot" PARTUUID="2b3b10b1-a458-481e-872c-bada7d244b13"
Note that it IDs the filesystem type as
TYPE="ext4"
Why?
Bios Boot Partition should have NO filesystem.
Is blkid correct? Is there, or isn't there a fs on that partition?
if there isn't, what's causint the 'false' report?
If there IS, how do I make sure there isn't?
