Since quite a while I have been patching /lib/rcscripts/addons/udev-start.sh to use my specified mount option for number of inodes. Without it, I get "no space left on device" errors on boot-up when udev tries to create nodes on /dev. I dont know what the default nr_inodes is, or how it is calculated. My patch is in the URL. In /etc/udev/udev.conf I set tmpfs_size="256k" and tmpfs_inodes="3k" Reproducible: Always jakub@gentoo.org 2007-09-24 05:59:40 0000 Don't refer to external links for patches, please. We have attachments feature for this. zzam@gentoo.org 2007-09-24 09:13:21 0000 From /usr/src/linux/Documentation/filesystems/tmpfs.txt: nr_inodes: The maximum number of inodes for this instance. The default is half of the number of your physical RAM pages, or (on a machine with highmem) the number of lowmem RAM pages, whichever is the lower. On my system the tmpfs has 128738 inodes. # df -i /dev/ Filesystem Inodes IUsed IFree IUse% Mounted on udev 128738 3394 125344 3% /dev So for systems with low number of physical RAM pages this could be too low. Can please give info about how low this is for you. zzam@gentoo.org 2007-09-24 19:55:46 0000 This is now implemented in udev-115-r6 gentooperson@yahoo.com 2007-09-24 20:16:29 0000 Created an attachment (id=131799) The file from the URL Here's the patch, as an attachment. gentoo@kolla.no 2007-09-24 21:53:38 0000 (In reply to comment #2) > From /usr/src/linux/Documentation/filesystems/tmpfs.txt: > nr_inodes: The maximum number of inodes for this instance.

Istead of messing up my /dev, I made a new filesystem for the test using the default values. cubesmurf ~ # free total used free shared buffers cached Mem: 20036 18576 1460 0 4 10676 -/+ buffers/cache: 7896 12140 Swap: 16376 0 16376 cubesmurf ~ # mkdir /bla cubesmurf ~ # mount -t tmpfs none /bla -o exec,nosuid,mode=0755,size=10M cubesmurf ~ # df -i /bla Filesystem Inodes IUsed IFree IUse% Mounted on none 2504 1 2503 1% /bla The problem is ofcourse: cubesmurf ~ # find /dev/ | wc -l 2753 so my /dev is now mounted with size=256k,nr_inodes=3k and hence looks like: cubesmurf ~ # df -i /dev Filesystem Inodes IUsed IFree IUse% Mounted on udev 3072 2752 320 90% /dev Thanks for fixing this, I wa hoping that I can avoid the patch in the future, it's so annoying when I forgot about it :) gentoo@kolla.no 2007-09-24 23:39:13 0000 (In reply to comment #3) > This is now implemented in udev-115-r6 Great, works fine!
