INCIP2 BTRFS UNTUK PROXY CACHE

berawal dari kompor mledug-nya filesystem btrfs, dan ZFS hanya jalan under unix base, not linux base, jadi penasaran coba btrsf di proxy

Sekilas Info BTRFS

Code:

Btrfs is a new copy on write filesystem for Linux.
Main Btrfs features include:

    * Extent based file storage (2^64 max file size)
    * Space efficient packing of small files
    * Space efficient indexed directories
    * Dynamic inode allocation
    * Writable snapshots
    * Subvolumes (separate internal filesystem roots)
    * Object level mirroring and striping
    * Checksums on data and metadata (multiple algorithms available)
    * Compression
    * Integrated multiple device support, with several raid algorithms
    * Online filesystem check
    * Very fast offline filesystem check
    * Efficient incremental backup and FS mirroring
    * Online filesystem defragmentation

pastikan sources list nya sudah di update

Code:

deb http://kambing.vlsm.org/ubuntu lucid main restricted universe multiverse
deb  http://kambing.vlsm.org/ubuntu  lucid-updates main restricted universe multiverse
deb  http://kambing.vlsm.org/ubuntu lucid-security  main restricted universe multiverse
deb  http://kambing.vlsm.org/ubuntu lucid-proposed  main restricted universe multiverse
deb  http://kambing.vlsm.org/ubuntu lucid-backports main restricted universe multiverse

install brtfs-tools dan probing brtfs

Code:

apt-get update 
aptitude install zlib1g-dev zlibc  btrfs-tools bzip2
modprobe libcrc32c zlib_inflate zlib_deflate btrfs

cek apakah module sudah terload di system :

Code:

lsmod |grep -i   btrfs

jika sudah tinggal format/convert saja,


utk format partisi ke btrfs


contoh :

Code:

mkfs.btrfs /dev/sdxx

untuk convert :

Code:

Must run fsck first
fsck.ext4 -f /dev/xxx

Convert from Ext3/4-> Btrfs
#btrfs-convert /dev/xxx

kalau sudah sukses test dengan mount

Code:

#mount -t btrfs /dev.sdxx /cachexxx

cek dengan perintah mount :

Code:

#mount
/dev/sda3 on /cache type btrfs (rw)

jika ingin permanin saat boot, edit /etc/fstab


misal :

Code:

/dev/sda3  /cache          btrfs  noatime,compress,noacl,barrier=0   0 1

selanjutanya step2nya seperi biasanya

Code:

#chown proxy:proxy /cachexx
#chmod 777 /cachexxx
#squid -z
#/etc/init.d/squid start

thats its,

TESTED ON UBUNTU LUCID
