Not much, I do not know the precise number but about gigabyte should be enough (and far less when you omit aio and fs stress tests). > $ LANG=C LC_ALL=C df -T > Filesystem Type 1K-blocks Used Available Use% Mounted on > rootfs rootfs 17753424 12825524 4003024 77% / > udev devtmpfs 1960968 4 1960964 1% /dev > tmpfs tmpfs 788020 888 787132 1% /run > /dev/sda2 fuseblk 465546236 107358584 358187652 24% /host > /dev/loop0 ext4 17753424 12825524 4003024 77% / > none tmpfs 5120 0 5120 0% /run/lock > none tmpfs 1970048 156 1969892 1% /run/shm > > Can I use a different partition where I have more disc-space available? LTP uses TMPDIR env variable for that (and defaults to /tmp/ when TMPDIR is not set). -- Cyril Hrubis chrubis@suse.cz ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Ltp-list mailing list Ltp-list@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/ltp-list
