[SOLVED] Pogoplug E02, u-boot, and roots

[embeddedtim]

Hi!

Pogoplug E02.

On 'mount', I see several options under my root ext3 fs:

$this->bbcode_second_pass_code('', '/dev/sda1 on / type ext3 (rw,relatime,user_xattr,acl,barrier=1,nodelalloc,data=ordered)')

My /etc/fstab is effectively empty (just some comments).

Where are these FS options coming from? I've looked through the u-boot environment variables (via fw_printenv) and haven't found anything that looks like the above settings. "tune2fs -l" doesn't show much and dmesg has the following lines:

$this->bbcode_second_pass_code('', '[ 19.604552] EXT4-fs (sda1): mounting ext3 file system using the ext4 subsystem
[ 19.797114] EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: (null)
[ 19.797158] VFS: Mounted root (ext3 filesystem) on device 8:1.')

Thanks for any/all help!

Those are defaults defined at format time and/or generic defaults for fs. You can add an fstab entry to remount rootfs with the options you like

Oops! I forgot to reply back to my own thread!

Yeah, I found that out a few days ago by grepping through the kernel init and ext4 module.

Thanks moonman!
