FileVault 2 + Mavericks upgrade = massive FAIL

Today, since I was using my Macbook Pro, I figured I’d upgrade OS X. Haha. What a mistake.

So. My Macbook Pro was running Mountain Lion with FileVault 2 enabled. Before that, it was running Lion, and if my recollection is correct, it was using FileVault 2 as well, so the upgrade to Mountain Lion preserved that properly.

The upgrade to Mavericks didn’t.

After the installation and the following reboot, and after a few seconds with the Apple logo and the throbber, I would be presented the infamous slashed circle.

Tried various things, but one of the most important information I got was from booting in verbose mode (hold Command+V when turning the Mac on ; took me a while to stumble on a page that mentions this one), which told me, repeatedly “Still waiting for root device”.

What bugged me the most is that it did ask for CoreStorage password before failing to boot, and it did complain when I purposefully typed the wrong password.

In Recovery mode (hold Command+R when turning the Mac on), the Disk Utility would show me the partition that was holding the data, but greyed out, and without a name. In the terminal, typing the diskutil list command displayed something like this:

/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *240.1 GB   disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
   2:                  Apple_HFS                         59.8 GB    disk0s2
   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3
   4:       Microsoft Basic Data Windows HD              59.8 GB    disk0s4
   5:                  Apple_HFS Debian                  9.5 MB     disk0s5
   6:                  Linux LVM                         119.6 GB   disk0s6

(Yes, I have a triple-boot setup)

I wasn’t convinced Apple_HFS was the right thing for disk0s2 (where the FileVault storage is supposed to be), so I took a USB disk and created an Encrypted HFS on it with the Disk Utility. And surely, the GPT type for that one was not Apple_HFS, but Apple_CoreStorage.

Having no idea how to change that under OS X, I booted under Debian, and ran gdisk:

# gdisk /dev/sda
GPT fdisk (gdisk) version 0.8.8

Partition table scan:
  MBR: hybrid
  BSD: not present
  APM: not present
  GPT: present

Found valid GPT with hybrid MBR; using GPT.

Command (? for help): p
Disk /dev/sda: 468862128 sectors, 223.6 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): 3C08CA5E-92F3-4474-90F0-88EF0023E4FF
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 468862094
Partitions will be aligned on 8-sector boundaries

   2          409640       117219583   55.7 GiB    AF00  Macintosh HD
   3       117219584       118489119   619.9 MiB   AB00  Recovery HD
   4       118491136       235284479   55.7 GiB    0700  Microsoft basic data
   5       235284480       235302943   9.0 MiB     AF00  Apple HFS/HFS+
   6       235304960       468862078   111.4 GiB   8E00  Linux LVM

And changed the type:

Command (? for help): t
Partition number (1-6): 2
Current type is 'Apple HFS/HFS+'
Hex code or GUID (L to show codes, Enter = 8300): af05
Changed type of partition to 'Apple Core Storage'

Command (? for help): w

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!

Do you want to proceed? (Y/N): y
OK; writing new GUID partition table (GPT) to /dev/sda.
Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot.
The operation has completed successfully.

After a reboot under OS X, it still was failing to boot, with more erratic behaviour. On the other hand, the firmware boot chooser wasn’t displaying “Macintosh HD” as a choice, but “Mac OS X Base System”. After rebooting under Recovery again, I opened the Startup Disk dialog and chose “Macintosh HD” there.

Rebooted again, and victory was mine, I finally got the Apple logo, and then the “Completing installation” dialog.

In hope this may help people hitting the same problem in the future. If you know how to change the GPT type from the command line in Recovery (that is, without booting Linux), that would be valuable information to add in a comment below.

怒り、失望、ストレス発散

I started learning japanese calligraphy a few months ago, with no prior experience with a brush and ink. It is an interesting endeavour. For various reasons, I had to skip class for a few weeks, but after the past ten days, I needed some stress relief on paper.

日本へ引っ越し

Today, May the 30th, was my last day as a Mozilla employee. In a couple weeks, my wife, my cat and I will be on board of a flight heading about ten thousand kilometers east, and most of our stuff will be in some container on a boat. We’re moving to Japan. As adventurous as this may sound, I’m not venturing into unknown territory. My wife is Japanese, and I’ve lived there for close to 15 months. A long time ago, arguably.

I’m not actually leaving Mozilla. I’ll be back as a contractor, hopefully around the 25th of June. So as far as my fellow coworkers are concerned, I’ll be going on a long-ish vacation and changing timezone (but I’ll probably be around in the meanwhile on irc or bugmail, with high latency).

Jump-starting in a different country is not something really easy to pull off, and working for Mozilla as a remotee has been a key element in being able to do so. Although I’ve made it clear when I joined Mozilla that this would eventually happen, I’m thankful I can now actually do it.

Turning 30

… is not much different than turning 29. Maybe turning 0x20 will make a difference…

Back from vacation

Well, it’s been a few days, already, but I’m back from vacation, and the website too. It happened that for some reason the ADSL connection decided to die a few days only after my departure, leaving the site unavailable for 3 weeks.

Meme time: What american accent do you have ?

What American accent do you have?
Your Result: The Northeast

Judging by how you talk you are probably from north Jersey, New York City, Connecticut or Rhode Island. Chances are, if you are from New York City (and not those other places) people would probably be able to tell if they actually heard you speak.

ただいま!

I’m back from Japan. Time went too fast… Met a lot of people we hadn’t seen for a while, had a great time. Only problem is that I’m totally jetlagged. Woke up at 3am this morning, and decided to actually do something after trying to sleep some more for an hour.

The downside of holidays is the 4000+ mails (excluding spam) that got in my mailbox. I’ve already gone through most of the new bug reports and have been able to vote for the last GR that was issued while I was away.

One of the most annoying problem that was raised during my vacation is this Firefox trademark issue. We’ve been avoiding to change the package name for a while. We got agreements to use the Firefox name when we had to drop the “Mozilla” part of “Mozilla Firefox”, and now it seems they (again) changed their mind.

I really think we should go with the iceweasel name because this name is already widespread as the “debian may rename firefox this way” name. It is even in wikipedia.

On other news, we bought a MacBook and a Nikon Coolpix S6 for Miki, and a (already broken) PSP as well as some books for me. I’ll write more on these in coming posts.
