What is the biggest file system that can be > created with FreeBSD 3.0? With 4.4BSD, UFS went to 64 bit pointers, which implies a maximum file size of 1.8 * 10**19 bytes. I don't know if there are other restrictions (apart from hardware availablity) to restrict the size to less than this, but I do know that somebody recently created a 72 GB file system on a FreeBSD system: > df -k Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/da0s2a 63503 21274 37149 36% / /dev/da0s2f 63503 1 58422 0% /tmp /dev/da0s2g 1714353 694290 882915 44% /usr /dev/da0s2e 63503 2212 56211 4% /var procfs 4 4 0 100% /proc /dev/vinum/bigvol 69109710 10056279 53524655 16% /alexandria Elsewhere I've heard of (unspecified) problems limiting file size to about 500 GB. These could be related to addressability, and wouldn't necessarily apply to the file system.
