Message-ID: <5400ECBC.5090301@gmx.de> (raw)
At as 32 bit KVM I run these 2 commands:
tfoerste@n22kvm ~ $ mkdir /mnt/ramdisk/btrfs; truncate -s 97M /mnt/ramdisk/btrfs.fs; /sbin/mkfs.btrfs /mnt/ramdisk/btrfs.fs; sudo su -c "mount -o loop,compress=lzo /mnt/ramdisk/btrfs.fs /mnt/ramdisk/btrfs; chmod 777 /mnt/ramdisk/btrfs"
tfoerste@n22kvm ~ $ D=/mnt/ramdisk/btrfs; while [[ : ]]; do cd ~; sudo rm -rf $D/t3; mkdir $D/t3 || break; cd $D/t3; mkdir -p v1/v2; for i in $(seq 0 99); do touch v1/v2/f$i; mkdir v1/v2/d$i; done; trinity -C 4 -N 100000 -V $D/t3/v1/v2; echo; echo " done"; echo; sleep 4; done
After a short while the syslog was flooded with :
