$MFTMirr does not match $MFT (record 0).

Well, we had a nice wind storm here last night. Power went out, and the fileserver had problems remounting one of it's 6 NTFS hard drives.... normally NTFS volumes would be mounted by Windows and the OS would simply run a disk check, and clean up any problems itself.

But my file server is a FreeBSD unix system. And running NTFS filersystems on Unix is not foolproof. Anyways, the error I was seeing was "$MFTMirr does not match $MFT (record 0)"

here's what I did to fix the drive:


# sudo -i
# ntfsfix /dev/hdc1
# ntfs-3g /dev/hdc1 /mnt/ntfs -o force


that fixed the MFT table on the problem NTFS volume, and I was back up in just a few minutes.

Serving Windows files from Unix

For the past 10 years, I have had 2 separate eco-systems on my home network. One was a Unix net, the other a Windows net. Rarely did one mingle with the other. Life was easy, and no one complained.

But I had to go and mess it all up.

My development hardware of choice is no longer a server, no longer a desktop... but a 17" laptop.
I currently have it Triple booting Vista, Mac OSX (hacked), and Debian Linux.
Under Vista I run a few virtual OS's using VMWare... so I'm pretty much self sufficient on this one machine.


So I moved all my windows machines down into the server room (actually it's just a corner of the garage), and put FreeBSD on all of them.

Anyways...
I still wanted to serve up my Vista laptop with music & video, as well as my livingroom laptop & xbox.
I also store a heck of alot of data files from my various projects.... and would like to keep them all on a similar filesystem format.

I though about converting the whole thing (8 hard drives of data - approx 2TB) and running it off an unix NFS server. But as the xbox and living room media center don't play well with NFS, I decided to run a Samba server instead, keeping the data on the original NTFS partitions.

Here's how I set up the main file server (running FreeBSD)


// grabed the ntfs-3g package
//
# pkg_add -r ntfsprogs
# pkg_add -r fusefs-ntfs
//or instead of packages, ports could be used:
# cd /usr/ports/sysutils/ntfsprogs/ && make install clean
# cd /usr/ports/sysutils/fusefs-ntfs/ && make install clean

// make sure gets loaded at boot...
//
# add fusefs_enable="YES" to /etc/rc.conf.
# add fuse_load="YES" to /boot/loader.conf.

// fix freebsd's limited mounts
//
# mv /sbin/mount_ntfs /sbin/mount_ntfs.bak
# ln -s /usr/sbin/mount_ntfs-3g /sbin/mount_ntfs

// make the hosting directories
//
# mkdir /mnt/win/projects
# mkdir /mnt/win/resources
# mkdir /mnt/win/media
# mkdir /mnt/win/apps

// mount ntfs drives
//
# vi /etc/fstab
// add the ntfs drives...
/dev/ad2s1 /mnt/win/projects ntfs rw,late,uid=nobody,umask=000 0 0
/dev/ad3s1 /mnt/win/resources ntfs rw,late,uid=nobody,umask=000 0 0
/dev/ad4s1 /mnt/win/media ntfs rw,late,uid=nobody,umask=000 0 0
/dev/ad6s1 /mnt/win/apps ntfs rw,late,uid=nobody,umask=000 0 0


// create our symbolic links so that they are available to samba
//
mkdir /var/pub
# ln -s /mnt/win/projects/var/pub/projects
# ln -s /mnt/win/resources/var/pub/resources
# ln -s /mnt/win/media/var/pub/Media
# ln -s /mnt/win/apps/var/pub/Apps



-----------------
2) Install Samba
-----------------


// install filesystem driver
//
# pkg_add -r samba3
# vi /usr/samba/lib/smb.conf

// make sure it starts at runtime
//
# vi /usr/local/etc/rc.d/

// edit samba conf
// note: BATLOGIC is the name of my home network....
# vi /usr/local/etc/smb.conf
workgroup = BATLOGIC
server string = Pearl Samba Server
security = share
hosts allow = 192.168.1. 192.168.2. 127.

// add the share definition
//
[pub]
path = /pub
public = yes
writable = yes
printable = no



// start/restart the Samba service
# /usr/local/etc/rc.d/samba restart




everthing has been running smooth, and the Samba server is pretty responsive

What's on my net. (vive la révolution!)

I purchased a new Laptop last month, it's powerful enough to do all my development work on it - So my previous workstation has been relegated to menial tasks.

I spent yesterday refreshing my home network - several went from Windows machines to FreeBSD machines (vive la révolution! ).... others were re-purposed....


Here's my home network setup:


Swan - (My Main system) - laptop - Vista - Dell Studio 1735 Intel T9500, 4gb ram, ATI 3650HD. It originally came with a T5750... I bought a T9500 from Newegg and plugged her in.

Flynn - (Print Server) - laptop - Win XP - Compaq Evo n610c, Pentium 4 2ghz, 756mb ram. It's serving a Canon MF3200 - which only has windows drivers.

Thor - (Living room - surfing) - laptop - Vista - HP DV9000, AMD Turion X2 TL50, 1.6ghz 4gb ram. It a 17" - same as the Dell.

Scarecrow - (Firewall) - FreeBSD 6.0 - AMD Athlon 2000+ 1.67ghz, 512meg ram (setup to use pfPorts)

Pearl - (File Server) - FreeBSD 7.0 - AMD Athlon 64 3200+ x2, 2g ram, 1.5TB total hard drive space on 5 drives

Heron - (Web Server, Test) - FreeBSD 7.0 - AMD duron 1.4ghz, 1gb ram, 250gb HD

Tron - (CVS source code repository) - FreeBSD 6.0 - Intel 920 dual, 4gb RAM, 2x250GB sata drives. This was my old development machine.

Ma3a - (Test machine) - HPUX - HP 712/100 PARISC, 100mhz, 160meg ram, 4gb external SCSI drive, 2 tape drives... useful for network penetration testing....



I have everything patched into a DLink DES-1026G 24-Port 10/100 + 2 Gigabit 1000BASE-TX Switch. I bought it on ebay brand new for $30 around 5-6 years ago; a great deal.

I also have a Netgear WNR834B Wireless N router, and another SMC barricade Wireless B router.....

I have a lot of old (non networked) machines from the 1980's and 1990's - various Apple Mac's classics, Apple II's, a Tandy COCO, several old IBM 8088's, and 80286, 80386's...... lots of old systems from the 1980's and early 1990's). Most are in storage bins only to be booted up every other year to make sure they're not bricked.
None of these have ethernet - but all have modems. I'd love to try and wire them to an internal homebrew PBX and connect them to my network one day....
