At least not with XFS within XFS. You can only test for maximum filesize. If XFS can be larger than that, you need a filesystem which can carry an even larger file. Maybe ZFS on Linux or so? BTRFS doesn´t go beyond 8 EiB per file as well: merkaba:/mnt#1> mkfs.btrfs -n 16384 -l 16384 /dev/merkaba/zeit WARNING! - Btrfs Btrfs v0.19 IS EXPERIMENTAL WARNING! - see http://btrfs.wiki.kernel.org before using fs created label (null) on /dev/merkaba/zeit nodesize 16384 leafsize 16384 sectorsize 4096 size 20.00GB Btrfs Btrfs v0.19 merkaba:/mnt> mount /dev/merkaba/zeit zeit merkaba:/mnt> cd zeit merkaba:/mnt/zeit> truncate -s1E canitgetcrazierthanthat.img merkaba:/mnt/zeit> truncate -s2E canitgetcrazierthanthat.img merkaba:/mnt/zeit> truncate -s3E canitgetcrazierthanthat.img merkaba:/mnt/zeit> truncate -s4E canitgetcrazierthanthat.img merkaba:/mnt/zeit> truncate -s5E canitgetcrazierthanthat.img merkaba:/mnt/zeit> truncate -s6E canitgetcrazierthanthat.img merkaba:/mnt/zeit> truncate -s7E canitgetcrazierthanthat.img merkaba:/mnt/zeit> truncate -s8E canitgetcrazierthanthat.img truncate: ungültige Zahl „8E“: Der Wert ist zu groß für den definierten Datentyp merkaba:/mnt/zeit#1> LANG=C truncate -s8E canitgetcrazierthanthat.im truncate: invalid number '8E': Value too large for defined data type merkaba:/mnt/zeit#1> ls -lh insgesamt 0 -rw-r--r-- 1 root root 7,0E Mär 11 23:09 canitgetcrazierthanthat.img Thanks, -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7 _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
