From 9b44896352f63f1417e241a193267a6ffdb72017 Mon Sep 17 00:00:00 2001 From: Mohammed Sadiq Date: Fri, 29 Sep 2017 08:52:02 +0530 Subject: [PATCH] doc: Suggest decreasing bytes per inode. By default bytes per inode is 16KiB. As the store files can be really small the inode space may get filled and errors regarding no empty space begins to appear. Reducing the size to 8KiB has an overhead of about 16MiB per GiB reserved for inode, better than having lots of cannot be used partition space. * doc/guix.texi (Disk Partitioning): Suggest to decrease bytes per inode for small partitions. --- doc/guix.texi | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/doc/guix.texi b/doc/guix.texi index 1b329d255..a150fa024 100644 --- a/doc/guix.texi +++ b/doc/guix.texi @@ -7998,6 +7998,17 @@ partition lives at @file{/dev/sda1}, a file system with the label mkfs.ext4 -L my-root /dev/sda1 @end example +As the store (@pxref{The Store}) shall be having lots of directories, +symbolic links, and small files, the inode space may run out before +the disk space is filled, especially if the partition size is small. +Decreasing the bytes per inode shall be better to avoid related issues. +So, with partition @file{/dev/sda1}, and with a label @code{my-root}, +bytes per inode can be set with: + address@hidden +mkfs.ext4 -L my-root -i 8192 /dev/sda1 address@hidden example + @cindex encrypted disk If you are instead planning to encrypt the root partition, you can use the Cryptsetup/LUKS utilities to do that (see @inlinefmtifelse{html, -- 2.14.1
