Unknown filesystem error [solved]

I just updated arch and now when I try to mount my usb harddrive I get this error:
# mount /mnt/usbdrive
mount: unknown filesystem type 'vfat'
Anyone know whats up?

I met the same problem.
the key is that the kernel is updated ( e.g. from 2.23 -> 2.24 ).
the vfat kernel module reside in difference directory (/lib/modules/XXXx-2.24/)after update.
but the kernel version in /proc is the old one , until you reboot.
if you don't reboot, when load the vfat module, the insmod will search the /lib/modules/`uname -r` , which can found nothing to load. well, what you get is nothing but some string like
# modprobe vfat
FATAL: Could not load /lib/modules/2.6.23-ARCH/modules.dep: No such file or directory.
so, you can understand why you are happy now.

[SOLVED] grub "unknown filesystem" error for big partition layout

Last night / this morning I copied the root and swap partitions of an Arch Linux installation (stushiba) I had on an old Toshiba hard drive, as well as the "system reserved" and other partitions of a Windows 8 install (stuzate) on another 500GB hard drive, onto a new 2TB Western Digital hard drive using Gparted via an external Arch environment I run off of a microSD card + adapter (sturling).
After doing so, I installed GRUB to the new drive to the best of my ability, but when I try to boot the system with just that drive, this is what I see:
GRUB loading.
Welcome to GRUB!
error: unknown filesystem.
Entering rescue mode...
grub rescue>
Running ls doesn't find anything:
grub rescue> ls
(hd0) (hd0,msdos4) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1)
grub rescue> ls (hd0,msdos4)
(hd0,msdos4): Filesystem is unknown.
grub rescue> ls (hd0,msdos3)
(hd0,msdos3): Filesystem is unknown.
grub rescue> ls (hd0,msdos2)
(hd0,msdos2): Filesystem is unknown.
grub rescue> ls (hd0,msdos1)
(hd0,msdos1): Filesystem is unknown.
The system should be on (hd0,msdos3) - it's ext4, and, if I insert the old Toshiba hard disk to the system and select that as my boot device in BIOS, it boots from the partition on the old drive's grub menu, into the partition in the new drive (because they have the same UUID), so the partition's definitely readable/bootable. (I've tried both regenerating the grub menu and installing grub from this boot scenario, with no change.)
(That said, if I enter a console on my system with a working GRUB installation and do an ls on that partition, I get more "unrecognized filesystem" messages.)
Once the new partition had loaded, I ran
sudo grub-mkconfig -o /boot/grub/grub.cfg
and rebooted, but GRUB was still broken.
I tried fixing this by rebooting into the latest installation media, with only the new hard drive plugged in, and running
mount /dev/sda3 /mnt
arch-chroot /mnt
modprobe dm-mod
grub-install --recheck /dev/sda
But that still hasn't fixed anything: I still get the "error: unknown filesystem." message whenever I try to do anything in GRUB.

This is the output when running from sturling (neither partition booted).
/dev/sda is the new disk, /dev/sdb is the microSD card I'm running the system off of, and /dev/sdc is the old disk.

[SOLVED] Grub boots to rescue mode err: unknown filesystem every drive

So I installed Arch and it all seemed to go reasonably well (well, had a little trouble installing GRUB to begin with, but I think that's just because I needed a BIOS boot partition at the start of the drive). I installed it onto a 4TB I have, which due to its size has a GPT partition table even though my mobo (Gigabyte GA-P67A-UD4-B3, don't think it matters though) uses a regular old BIOS. Initially it was two partitions, the Microsoft reserved partition then a big NTFS data partition. I shrunk the NTFS partition and then made (in this order on the disk, starting at third) an ext4 partition for /boot, a swap partition, and a big btrfs partition (in which I created subvolumes for /, /etc, /home and /var). GRUB wouldn't install (I forgot the exact error) but what I could find suggested it was because there needed to be room for it at the start of the disk, so I deleted the Microsoft reserved partition (Windows is installed on an SSD, and its bootloader is on another hard drive entirely, so I didn't think I needed it) and created an empty partition with the right code using gdisk, then I could install GRUB to the 4TB HDD.
Unfortunately, when I try to boot into GRUB it immediately comes up with error: unknown filesystem and dumps me at the GRUB rescue prompt. Using ls, I can see my HDDs and their partitions, but whenever I try to use (for example) ls (hd0,gpt3)/ - which I think should probably be the ext4 boot partition, but it does this for everything - it just says error: unknown filesystem again.
This seems pretty close to (if not exactly the same as) my problem, so I tried what he suggested, but when I tried to run the command he says worked, (grub-install --recheck --disk-module=native /dev/sda) - and don't worry, I didn't do that blindly, I know /dev/sda is my 4TB HDD - I just get the error grub-install: --disk-module: (PROGRAM ERROR) Option should have been recognized!?. So I'm all out of ideas and I've been trying for a few hours. Please help me, before I go insane... more insane. I can boot the USB drive I used to install Arch and chroot into my installation, but I haven't found a way to actually boot the installation yet.
SOLVED: Apparently the partition I was using for /boot was too far back on the drive (past the first 2TB). When I shuffled partitions around so that the /boot partition was near the start of the drive (it starts at sector 2048 now!) that seemed to fix it.

Tried using insmod btrfs in the grub rescue shell last night. Didn't work, can't remember if the insmod command itself gave me an error or whether it still couldn't see any files or anything. Tried it again today, but that was after I converted /dev/sda3 back to ext4 and mounted it at /boot (since it being ext2 wasn't working, and not using it wasn't working, so I figure what's the harm) and I just got error: unknown filesystem.
Anyway: using grub-install from outside chroot seems to work (still can't use --disk-module), but grub-mkconfig just generates this:

I'm not an expert on GRUB configuration files, but I figured that even if that didn't just boot me straight to the rescue shell, it wasn't going to boot anything... other than memtest86+ maybe. So I went back into chroot and run grub-mkconfig and it generated this:

Still didn't work though.
I don't know grub config, but is the UUID specified in
linux /vmlinuz-linux root=UUID=b21e6211-5e7a-4769-9f53-b9b5d554a242 rw rootflags=subvol=root quiet
supposed to be the UUID for /boot or /? Because the UUID there is for the btrfs partition being mounted at / (which I guess would explain why it has the correct subvol listed, which I'm not sure if it's necessary, given that should be the default subvolume). So... that's probably alright (just something that stood out to me).
As for installing grub on another disk: I suppose I could try, though I'd rather keep it on one drive if I can (sometimes it gets complicated enough having Windows and my Windows bootloader on different drives... I should probably try moving the Windows bootloader to the SSD where Windows is installed. Would it matter which drive? The options are:
sda: 4TB, GPT table, the one I'm having problems with now
sdb: 2TB, MBR table, nothing in boot sector AFAIK
sdc: 240GB SSD, GPT table, would rather not use it since Windows is installed on there, even if its bootloader isn't
sdd: 1TB, MBR table, nothing in boot sector AFAIK
sde: 500GB, MBR table, has the Windows bootloader so I'd rather not mess that up (although given it's the smallest and I have no free SATA ports, it'll be next to go when I need more space, so I might want to move the bootloader)
(sdf and sdg which appear in lsblk earlier are just USB flash drives, and I'd rather not have to rely on having to use one of them to boot Linux).
As for repartitioning /dev/sda: as long as I can do it non-destructively, sure. Well I mean non-destructively for the NTFS partition, which is mostly full of Steam games (and I might have enough room on other drives and portable drives to keep the rest safe), but on my crappy Australian internet connection (aren't they all) it'd probably take me a couple of weeks to redownload them. I don't mind if I have to get rid of the Linux partitions, I already tried going through the install again once before to try to get it to work, another time isn't going to matter. So I guess I could try using gparted to delete the Linux partitions, move the NTFS partition to the end of the disk, and recreate the Linux partitions in front of it (although moving that much data might take a while, so I'd probably want to do it overnight). For reference, right now it's:
128MB of unformatted space (where the Microsoft reserved partition was, but now it's flagged as a BIOS boot partition, even though it's far bigger than it needs to be for that, I didn't feel like moving the other partitions back just to claim less than 128MB)
~2.7TB NTFS data partition (important)
~1GB ext4 /boot partition
8GB swap partition
~1TB btrfs partition with subvolumes mounted at /, /home, /etc and /var

Fresh btrfs root partition cannot boot/unknown filesystem [solved]

Just reformatted my SSD with 3 partitions.
1) EFI
2) /boot (ext4)
3) / (btrfs)
I copied over my systefrom tars, adjusted the new fstab to use btrfs, I rebuilt my kernel images, and rebuilt grub.cfg in the chroot. When I reboot, I get:
Welcome to grub!
error: unknown filesystem
Entering rescue mode...
grub rescue>
Per the wiki, there should be no special setup steps to boot to a btrfs root with grub. When did I f-up?
/etc/fstab
LABEL=arch64 / btrfs defaults,discard,noatime,ssd,compress=lzo 0 0
LABEL=boot /boot ext4 defaults,discard,noatime 0 2
Excuse the short post, typing in a phone.

Yes, it is dropped to a GRUB rescue shell. I can boot if I manually type the following but WTF?! Why isn't grub doing this by itself?

[Solved]Wont boot after installing syslinux; unknown filesystem 'swap'

After installing syslinux to be my boot manager I can no longer boot into Arch, I can however boot into Windows 7. When I try to boot into Arch I get the following error.

[SOLVED] mount: unknown filesystem type 'ext2'

I probably have the most complicated first-time arch setup that you'll ever hear a n00b post. XD
I just finished setting up an encrypted arch box with a usb boot drive (it contains the key-file), but when I go to boot, the system reports the following:
mount: unknown filesystem type 'ext2'
Of all the things to break! Ext2???!
This is for the default boot mode, when boot into the fallback initramfs mode, the arch box boots up fine (although it takes 2 whole minutes). I think that the issue is that I'm missing a module in my mkinitcpio.conf file.
/etc/fstab file:
UUID=1245ASDF / btrfs discard,autodefrag,compress=lzo,rw,relatime,ssd,space_cache 0 0
UUID=2245ASDF /boot ext2 rw,noatime 0 2
UUID=3245ASDF none swap defaults 0 0
/etc/mkinitcpio.conf file:
HOOKS="base btrfs udev autodetect modconf block encrypt lvm2 filesystems keyboard fsck"
/etc/default/grub file:
GRUB_CMDLINE_LINUX="cryptdevice=/dev/sda:enc cryptkey=/dev/sdb2:ext2:/keyfile crypto=sha512:twofish-xts-plain64:512:0:"

Wow, there was literally a note about the exact issue I was having on the wiki...
https://wiki.archlinux.org/index.php/Mkinitcpio#MODULES
Note: If using reiser4, it must be added to the modules list. Additionally, if you will be needing any file system during the boot process that is not live when you run mkinitcpio — for example, if your LUKS encryption key file is on an ext2 file system but no ext2 file systems are mounted when you run mkinitcpio — that file system module must also be added to the MODULES list. See Dm-crypt/System configuration#cryptkey for more details.
PS: How do I mark an issue as solved?

[Solved]Can't install Thunar, 'index.theme exists in filesystem' error

Hi,
I'm trying to install Thunar via 'pacman -S thunar'. The packages downloaded fine, but after that, I get this output:
error: could not prepare transaction
error: failed to commit transaction (conflicting files)
hicolor-icon-theme: /usr/share/icons/hicolor/index.theme exists in filesystem
Errors occured, no packages were upgraded.
Any idea what's wrong? I would simply go and remove the conflicting file, but I don't know if anything's using it. I'm using a almost-fresh install of Arch with Openbox.
Last edited by vertimyst (2009-02-25 04:44:53)

Thanks for the advice - I made a backup of the file just in case before deleting it, and Thunar installed fine after that. Nothing seems broken (yet).
Thanks again!

How can I solve an "Unknown server error"?

I've been trying since YESTERDAY to download the Photoshop trial and it keeps saying that an "unknown server error" occurred with the message: "Sign in is currently unabailable. We are unable to access your account. Please try again later."
- Always when it happens I AM logged in on the website. It can't be a login issue
- I have already uninstalled and installed again the Creative Cloud app
- I have already restarted the computer
- I have already signed out and in again on the website
- I have already closed and opened the Creative Cloud window a thousand times
- And I have already tried later
I don't know what else to do, and this thing is delaying my work.

Hi Prii,
Please refer the KB : http://helpx.adobe.com/creative-cloud/kb/unknown-server-error-launching-cc.html

Sign in failed - Unknown server error (-2) when trying to sign in to new playbook

I get the message "Sign in failed - Unknown server error (-2)" when I try to login to the Blackberry ID page of a new playbook during initial setup. This prevents me from continuing and using my device. A similar error message appears when I tap "Forgot password?" which is An unknown error has occured. Please try again (-2)
I have tried what others have done when they have unknown error (-6) which is turn off playbook and plug into desktop manager then update to reflash, but I continue to get the same error.
I know my BB ID username and password are correct because I can login to the web with them. Not sure what to do next.

Just to test the simple things first, did you try to sign in using another credential?
If only yours fails, then is a RIM issue, otherwise is indeed your Playbook failure.

Can't Export Movie - Unknown Compile Error - Help!

I edited a 32 minute movie in Premiere Elements 10, and now I'm trying to export it. At some point during the export, and it seems to vary, I get an unknown compile error. I've been trying to export the movie for the past week and all I get is failure despite trying just about everything I've found written about how to solve this.
I have Win 7 Ultimate SP 1 running on a Lenovo desktop machine with an Intel Core 2 Quad CPU at 2.67 GHz, 4GB of RAM, 32 bit proc.
Premiere is installed on system C drive with 6 GB of free space.
Project and scrach disks are on D drive with 165 GB of free space.
Media files are on 2nd E drive with 50GB of free space.
Project and most source material is NTSC DV -- there are quite a few photos with motion, plus some iPhone HD video on the timeline, hundreds of clips in all plus narration, a few titles, etc.
Export destination folder is on D drive.
Everything will render to green lines atop timeline (sometimes it quits during render and I have to keep hitting Enter to continue rendering, but eventually it's all green)
So far I've tried:
- Reinstalling PE 10
- Reinstalling Quicktime
- Copying all the photos to their own separate folder
- Editing each photo slightly (outside of PE 10) and resaving to make sure none of the photos are corrupted
- Emptying the temp folder
- Deleting all the renders and cache files and letting them rebuild
- Exporting small pieces of the timeline to try to identify a bad clip -- this is a maddening process and I did find one clip that would generate the error, but I managed to export that to AVI and reimport and replace on timeline. It would be awfully nice if PE would just TELL ME which clip it doesn't like if in fact it's a clip error.
- Turning off the shadow / highlight feature I had on some clips, but this wasn't the issue, smaller sections with these clips exported fine
- Tried exporting to various formats: Vimeo SD, MPEG DV Standard, iPad Standard High Quality, AVI -- all result in the same error (the format I want by the way is Vimeo SD)
- Rebooting the machine and turning everything off that might possibly consume memory
This machine has never had problems exporting in the past. One thing I did try that worked -- installed PE 10 on another (less capable) Win 7 machine, and fed it all the media via an external drive. The other machine did the export fine (though it took a while given it is underpowered). This is nothing more than a work around though as I don't normally have access to this machine and I'm not done editing.
I'm at my wits' end! What else can I do to get this movie file to export?
Appreciate any help or clues you can provide to solve this mystery.

Oh, that is tragic!
I never had any issues with mine. Maybe it knew how respectful I was, having come from manual rewinds and a sync block? The Moviola was a godsend, at least for me. I am glad that I got to edit film, and on many setups, as some of that translated well to digital Video. Back when I was in film school, Video was 2" tape, and the only editing was by cutting at a 45 degree angle, and splicing the tape. There was not even deck-to-deck editing, way back then. Also, Video looked like crap, at least to my eyes. We could only use a switcher, to "edit," or do a feed to air. Looked like crap!
As for the Lexus, I can imagine all sorts of problems. My new LX-570 requires me to "Accept," when I put it into reverse, on the rear-view monitor! At least my wife's MB does not require that, but it is a 2011 model, so maybe the 2013 models will require that the user sign off on all sorts of "stuff."
Now, I can play Finding Nemo, for my rear-seat passengers, while driving, but the front-seat passengers cannot see it, which is just fine. When driving, I am not even a fan of hands-free calls, and declined most of the streaming stock quotes, etc. for XM/Sirius radio. NOT while I am driving. I will save that for reading the WSJ in the club at the airport.
Some years ago, our driver in London got a new BMW 7-series, and it allowed the playing of DVD's, even in the front, while driving. Not sure that I would want that, but such is life. At least his seats' ventilation system was "well-chilled," where ours' are just air. He almost froze my bum, showing off his new auto.
Now, working with PS, or PrE in an auto, or even on a mobile device, is just not something that I can wrap my old head around. I want a fast computer, with a big display, and cannot imagine editing Images, or Video, on any handheld (or auto) device.

Can't boot after system update: unknown filesystem type

After running a system update, including updating the kernel, I can't boot to the new kernel.
On booting, grub loads the kernel image, runs/loads udev, but then fails to mount the root partition with error:
mount: unknown filesystem type 'ext4'
I have tried reinstalling the 'linux' package via packman several times, also trying the --recursive argument to make sure all my dependencies were there, and after days of googling and tweaking my system, I'm at a loss.
Thank goodness I happened to keep a spare kernel laying around in /boot.
Thanks in advance.

The OP can read their partition initially though, it's only after udev that they can't.
Also, try adding "rootfstype=ext4" to your grub kernel line. Is your /boot on a separate partition or part of your / partition?

Unknown Server Error - Adobe Cloud Manager

Does anyone know the "true fix" for those of us that have Adobe Cloud Manger -- and get this error "Unknown Server Errror" when they try to log in, you are denied access because it says to try later.
I tried all the fixes Adobe has offered at this link. And, it did not work http://helpx.adobe.com/creative-cloud/kb/unknown-server-error-launching-cc.html.
I called and talked to tech support who gave me a temporary fix:
They said, create a new User Account on my laptop, sign in as that user, then download the Cloud Manager again, Log in.. And Yes, VOILA it worked.
Then they told me to delete the "test" user Account after I log in as myself agian -- and all would be well.
That's not exactly true. If you delete the USER account including all traces of files -- your are right back to where you were.
Which is, unable to launch the Cloud Manager under your original User ACCOUNT on your laptop.
I understand that I could keep the files from the alternate "Test User Account".
However, The thing is.. I pay a lot for this service, and I do not think that I should have to fix a bug that ADOBE should be fixing -- by creating a second "Test User Account" on my laptop.
Sorry for the rant -- with that said. Has anyone solved this puzzle? Thank you for your help.
I'm just sayin' Come on Adobe -- Really, Really, No Really.
