Hi,
I have found that mount command ignores [gmk] suffixes (GB, MB, kB) when tmpfs size is defined in fstab (or directly used with mount). Expected behavior is as follows (Debian linux): # mount -t tmpfs -o rw,nosuid,size=100m,mode=1777 tmpfs /xxx # df -h /xxx Filesystem Size Used Avail Use% Mounted on tmpfs 100M 0 100M 0% /xxx kfreebsd: # mount -t tmpfs -o rw,nosuid,size=100m,mode=1777 tmpfs /xxx # df -h /xxx Filesystem Size Used Avail Use% Mounted on tmpfs 7.0G 4.0K 7.0G 1% /xxx It must be defined in bytes: # mount -t tmpfs -o rw,nosuid,size=104857600,mode=1777 tmpfs /xxx # df -h /xxx Filesystem Size Used Avail Use% Mounted on tmpfs 100M 4.0K 100M 1% /xxx Which is ok if you know about it and define the size in you fstab in bytes (contrary to several Debian articles info). But the /lib/init/tmpfs.sh uses kilobytes in its calculations and return values (e.g. RET="${RET}k"), therefore the default size of tmpfs file systems calculated as percentage from memory size might be wrong. Basically, this change helped me: < RET="${RET}k" > RET=$((RET*1024)) however do not know whether it is not used also somewhere else. Regards Vaclav |
