Re: Cannot Log in after new install using BTRFS subvolumes

Hi Alvaro, As your system boots it means that / subvol is working. Try to boot the livecd and fix permissions on the /home subvolume's folders. They may be read only and so not working (try with a unsafe 777 recursive for all subvolume, then narrow it down) I think this can be the issue to fix.

Re: XFS on Mint? Or should I be using another fs?

you may experience some slowliness if enabling "discard".. this is due to kernel not implementing latest patches.

you may try installing liquorix kernel or disable "discard" and run occasionally "fstrim" to zero the empty space.

Re: Black screen when booting LMDE 201204 with Intel graphic

adding this to boot options in grub works great also on my DELL Latitude E6430 with HD4000 graphics

Code: Select all

i915.modeset=0
thanks a lot for pointing this solution!

now I can successfully install and run LMDE!

R: Re: Installing LMDE on BTRFS with lzo compression, almost

The BTRFS wiki says the opposite about Zlib and Lzo: https://btrfs.wiki.kernel.org/index.php/Compression Lzo is designed to be real-time, compromising on compression ratio. But you said you tested it and found Zlib to perform better? By testing it seems that speed is almost same. When i said zlib i...

R: Installing LMDE on BTRFS with lzo compression, almost

To make effective the changes you have to reboot if we are talking about your /. To have compression if you install it on plain btrfs then you mount root sub volume with compression, an rsync things there.. While copying it will compress. Lzo probably is best for compression but zlib is very lightwe...

Re: Installing LMDE on BTRFS with lzo compression, almost

My understanding is that you don't want to use the compress-force option because some files don't compress well and it will lower R/W speed. Is this not true? compress-force will force btrfs to TRY to compress all data that has to be written on SSD, it's done by CPU and will not degradate performan...

Re: BTRFS installation

Btrf can be faster if you use compression, I suggest zlib, also have TRIM option, good for SSD, but the most important thing is that you can snapshot your volumes, you can convert it in RAID kind of thing in future and this cag give you better performances than mdraid. http://penzoditutto.blogspot.i...

check my tutorial, you can find something useful:

this is about making separate subvolumes for home and root, but can apply to your case for many things.

Re: SSD For Dell Mini 1012

Of course it's possible to create subvolumes, but on SSDs they will not improve performance much (unlike harddisks where it's certainly worth having /home and / separated). If you're new to Linux then it's fine to install the whole system on one Btrfs partition which can be directly done from the M...

if you use the Btrfs filesystem instead of ext4 then it's automatically enabling TRIM and such that's not true, you've to set a mount option in /etc/fstab discard if you want better performance you can force zlib compression that's really cool. compress-force=zlib An example of fstab line to enable...

Re: XFS on Mint? Or should I be using another fs?

I've seen Btrfs at work, It's under developement, but it's stable enough: I use it in production for my virtual machine storage pool, and I can get far better results in terms of R/W performance than mdraid. It's really a great FS, RAID configuration is easy, flexible and you really can have a cool ...
