Is there any way of increasing the number of inodes for a file system
without increasing the size? I have a 16Mb tmp filesystem with 4100 inodes.
When our news feed arrives (Full feed via Telebit), it comes in faster than
it unbatches. The console reports "Out of inodes", and news reports "File
table full" and "Permission problems in directory /tmp". Rather than
increase the size of tmp (which is fine for our purposes), or use another
tmp directory elsewhere (requiring recompilation of news sources, which
people down the road may not be aware of), I would like to just increase the
number of inodes. Can it be done?

The console reports "Out of inodes", and news reports "File > table full" and "Permission problems in directory /tmp". Make sure you check "df -i" before rebuilding any file systems. The messages "Out of Inodes" and "File table full" on the console without filesystem qualifier indicate the incode inode table has filled. The solution for that is to use sysparam to up the numbers for the system. Unfortuneately, sometimes I have a feeling that the limits set in sysparam aren't reached before the console message appears (i.e., something else is a limitting factor).

If you decide to do so and you're running Umax 4.2 release 3.3 then invoke "create_fs" with the following options: create_fs -c 8 -i 512 /dev/filesystem This reduces the number of cylinders/group from 16 to 8 and specifies 512 bytes/inode. This should effectively double the number of inodes on your filesystem. If you're running Umax 4.3 beta 4.0 then you can invoke "mkfs" as follows: mkfs /dev/filesystem <size in sectors> 32 16 8192 1024 8 10 60 512 t All options other than the number of cylinders/group and bytes/inode are the default options. #Naresh Naresh Dharnidharka Encore Computer Corporation naresh@encore.com (508)-460-0500 ext 2742 #Naresh
