Unable to find root device

Hi,

I have an Arch install on my laptop with full disk encryption. Last week I got this error at start :
Unable to find root device /dev/mapper/vg-root.
I managed to fix it by chrooting in my system from a live usb, and reinstalling udev and linux.
Yesterday the error appeared again, I tried the same thing but it won't work.
I find this very weird, I can mount the vg-root volume from the live usb but it is not there at start ...

Any ideas ?
Thanks in advance

Re: Unable to find root device

I had problems with libreadline.so.6. Some programs, like awk, needing of libreadline.so.6. I make a link symbolic of version 7 to 6:

cd /usr/lib
ln -sf libreadline.so.7 libreadline.so.6

DO NOT MAKE STUPID SYMLINKS!!!

Partial updates are not supported. Update your entire system and things work.

Edit: And don't hijack threads, either.

Re: Unable to find root device

Perhaps try the rootdelay= boot parameter to instruct the kernel to wait a few seconds before trying to mount root. LVM may take some time to settle.

What happened to Arch's KISS? systemd sure is stupid but I must have missed the simple part ...

... and who is general Failure and why is he reading my harddisk?
