<astr> know anything about cryptsetup ubuntu/debain installs?
<whitequark> I have one
xiangfu has quit [Ping timeout: 265 seconds]
<astr> whitequark, I did a full install custom encrypted / . so no swap just /boot & / and no lvm. it works but I mounted / and added some files and now when I boot it and correctly enter my pass it doesn't complete boot with the error of the checksum not matching for root fs. how do I regenerate this checksum?
<whitequark> what is the error exactly?
<whitequark> and which FS?
<astr> ext4
<astr> did a FS check and that was fine no errors
<astr> I think it's becuase I modified / when the sytem wasn't booted and somewhere there is a checksum for / to see if it's been modified which is checked when I try to boot the system
<whitequark> there is no such checksum
<whitequark> what is the exact error you're getting?
<astr> ok well I enter my password and then I get the option of maintence shell or S for skip
<whitequark> can you take a photo of it or type the error exactly as it appears?
<astr> I forget exalty I think it was something like "checksum did not match"
<whitequark> well, I can't help you with that.
<astr> sigh ok, i'll reboot laptop. thank you for baring with me
<astr> not long now...
<astr> crypt_sdc5 cryptsetup setup usefully
<astr> press s to skip mounting or m for manual recovery
<astr> whitequark,
<astr> press S get continure to wait, or press S to skip.......
<astr> screen gone black no info even after pressing esc to get console
<astr> giving up killing it
<astr> hmnm
<astr> #2
<whitequark> that's not the entire message, is it?
<whitequark> also, "usefully"? wtf
<astr> hang on
<astr> opps sorry i mean : successfully
<whitequark> so where's the checksum error there?
<astr> trying to find it
<astr> ok so after cryptsetup: sdc5_crypt setup seccessfully then I get "Keys: Press S to skip mounting or M for manual recovery"
<astr> this time I press M instead of S
<whitequark> it should have printed something else before, then
<astr> in maintenance console: "root filesystem check failed."
<astr> a maintence shell with now be started
wolfspraul has quit [Quit: leaving]
<astr> control-d to reboot
<astr> so I see the error when I press M for manual recovery
<astr> "root filesystem check failed."
<astr> hmm what to do
<whitequark> so, this is simply a dirty filesystem
<whitequark> fsck it.
<astr> but I did a fsck with gpared allreadly
<astr> gparted
<whitequark> well, do it from the maintenance shell
<astr> I booted into my other install unlocked the encrypted partition and did a ....
<astr> ok
<astr> fsck /dev/mapper/sdc5_crypt I shall do
<astr> e2fsck: reports it as clean
<astr> I assume you don't need the files and blocks count?
<astr> arrr I wonder.....
<astr> no never mind
<astr> then again maybe mount for the dev point was the wrong one as /etc/mtab is not updated
<astr> ...
<astr> i'll try agian
<astr> cat /proc/mounts
<astr> how to get dev point for encrypted ext4 FS
<astr> hmm /etc/crypttab
<astr> oh no
<astr> thanks no it
<astr> why did i write thanks no it urgh
xiangfu has joined #qi-hardware
<astr> whitequark, arr ok just running fsck was all was needed
<astr> oh but yea fsck says clean for /boot partition and for ext4 / partition
<astr> well encryped device/dev point
<astr> "/dev/mapper/sdc5_crypt: clean, 21047/1908736 files, 1542919/7623680"
<astr> blocks
<astr> whitequark, not fixed, see above. when I said fsck was all was needed I meant just "fsck" not fsck <pram>
