Those values are very suboptimal. Whe creating a file system for large files, you should rather decrease the inode density (-i option). Using "-i 262144" should work fine, or even "-i 1048576" (larger values don't make much sense, though). Increasing block size and fragment size like that is not a good idea. In fact, in earlier versions of FreeBSD there were bugs which could lead to file system corruption when 64k block size was used. I don't know if those bugs have been fixed -- maybe nobody knows, because nobody uses such large block sizes, so they aren't extensively tested. ;-) However, you could try setting block size and fragment size to the same value, effectively disabling fragmentation (you don't really need fragments when you have only large files). For example, "-b 8192 -f 8192" should be OK. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co.
