Re: Kernel panic VFS unable to mount unknown block

So this happened again, while doing a proper sudo reboot, btw and I again had to put the card into another pi and fsck it. At least this time the damage was less severe, and the partition was mountable from the start. Anyways, to the point, I want to know what I can do to stop this from happening. F...

Re: mounts too slow(?) causes apps to create dirs in mount p

which service is misbehaving? are the dependencies set up correctly in the init script? what OS are you using? Raspbian Wheezy or Jessie or something else? What I think is happening is that the init script does not define a dependency for the mount to be finished and the service gets started too ea...

Re: mounts too slow(?) causes apps to create dirs in mount p

Putting in a hardcoded delay is the best that can be suggested? What happens when this clearly-variably situation changes a little bit again and it takes longer or shorter and breaks again - or other services now need to access the mount. Are my expectations too high? I assume there MUST be a way to...

Re: Distribution that is more up to date?

Well Arch may be good from a packages-up-to-date perspective, but it's a nightmare to install for a relative newb like myself - they have some decent documentation, but right now it seems like a lot of it is slightly out of date. Unfortunately I can't get LXDE working on it properly (no mouse/keyboa...

Hi guys I love my pi 2, but I'm a little tired of having to do as much messing around to get things dialed in as I do currently. It's a pain in the butt when the latest (or even, semi current) packages are not available on raspbian. I just want to use the darn thing, not become a linux expert. I've ...

Re: mounts too slow(?) causes apps to create dirs in mount p

I'm aware of sleep, thanks.

I don't really see an elegant way to use it however, since these are services that are automatically starting, and adding in a random delay for every start (on bootup or not) seems silly..

Re: mounts too slow(?) causes apps to create dirs in mount p

I guess I should clarify a bit - I think what happens is, the processes look for the drive directory structure, don't see it, and create their own directory structure. Then when the mount happens automatically, it's fails, because the mount point isn't empty. Either way I'm not sure how to fix this ...

Hey guys I have an external HD hooked up to my pi, and it mounts fine with sudo mount -a.

So somehow, I end up with my HD not mounted, and blan...

Re: Rasbiam ARMv7 optimization

Be aware that the biggest performance drag is a slow sd card. A slow sd can be class 10, 20mb/s, but it's the UNPUBLISHED stat of random queued writes that makes the difference.

This made my life very unpleasant for quite some time.
