How to Fix the Buffalo Linkstation NAS – Partition Not Found Error

Buffalo-LinkStation-220-1024x576-e90e950d78fb74df

Recently I picked up a Buffalo Linkstation 220 to play around with at home as I felt that I could use a bit of additional storage to play around with. Note that this previous statement is pretty much a lie. I have tons of storage, and was really just looking for an new toy to play around with. Basically I just had a few disks laying around that I wanted to put to use.

However, much to my dismay the I was unable to configure the device once I shoved in the disks, powered it up, and connected to it with the Buffalo Smart Phone Navigator. I figured that this was not a big deal however, so I tried the installable Windows App from my Windows 7 Vm. The Buffalo NAS Navigator was also able to connect to the device, however the device showed that it was currently booted in what was called “Emergency Mode”. Not sensing a real emergency, I did not panic.

See borrowed image below.

Fortunately the site that I borrowed the above image from (here) and this site (here) give advice on how to fix the issue. First step is to download the Buffalo Linkstation Firmware Updater that you can get here. Both pages advise you to modify the LSUpdater.ini file. However their instructions did not work for me. The exact changes, and the LSUpdater.ini in its entirety are below.


[Application]
Title = BUFFALO LinkStation Series Updater Ver.1.62
WaitReboot = 1200
WaitFormat = 600
WaitFileSend = 600
WaitDiscover = 120

[Target]
ProductID = 0x80000000
ProductID2 = 0x0000001D
ProductID3 = 0x0000300D
ProductID4 = 0x0000300E
ProductID5 = 0x00003011

Name = LinkStation

[Flags]
VersionCheck = 0
NoFormatting = 0

[SpecialFlags]
Debug = 1

At this point you launch the updater again, and select “Update“. This fully partitions the drives and then updates the firmware. This process takes a while, so be patient. Now you can launch the NAS Navigator and configure the device.

Solaris: How to Resize a Swap Partition….on a disk without any free slices

First lets detach the swap partition (submirror) on the secondary disk. Where d1 is the metadevice and d21 is the submirror

#metadetach d1 d21
d1: submirror d21 is detached

metaclear d21
d21: Concat/Stripe is cleared

Now lets format Secondary Disk (c1t1d1 in this example)

Below is the partition table of the disk that I am working with. Slice one will be resized using unallocated disk space. Add 1 to the last cylinder of slice 7 to determine your starting cylinder. In this case my new starting cylinder is 2691.

Total disk cylinders available: 14087 + 2 (reserved cylinders)
Part Tag Flag Cylinders Size Blocks
0 root wm 0 - 824 4.00GB (825/0/0) 8395200
1 swap wu 825 - 1031 1.00GB (207/0/0) 2106432
2 backup wm 0 - 14086 68.35GB (14087/0/0) 143349312
3 unassigned wm 1032 - 1038 34.78MB (7/0/0) 71232
4 var wm 1039 - 1657 3.00GB (619/0/0) 6298944
5 home wm 1658 - 2070 2.00GB (413/0/0) 4202688
6 stand wm 2071 - 2277 1.00GB (207/0/0) 2106432
7 stand wm 2278 - 2690 2.00GB (413/0/0) 4202688

Now resize the partition
In this case I am going to use the rest of the disk, which according to the information for partition two, ends @ cylinder 14087. Subtract 2691 from 14087, to determine how many cylinders your slice is going to be.

Enter partition id tag[swap]:
Enter partition permission flags[wu]:
Enter new starting cyl[825]: 2691
Enter partition size[2106432b, 207c, 1028.53mb, 1.00gb]: 11396c

Now save this new partition scheme

Enter table name (remember quotes): my_table

Then label your disk. As you can see below, my swap partition is now huge.

Part Tag Flag Cylinders Size Blocks
0 root wm 0 - 824 4.00GB (825/0/0) 8395200
1 swap wu 2691 - 14086 55.30GB (11396/0/0) 115965696
2 backup wm 0 - 14086 68.35GB (14087/0/0) 143349312
3 unassigned wm 1032 - 1038 34.78MB (7/0/0) 71232
4 var wm 1039 - 1657 3.00GB (619/0/0) 6298944
5 home wm 1658 - 2070 2.00GB (413/0/0) 4202688
6 stand wm 2071 - 2277 1.00GB (207/0/0) 2106432
7 stand wm 2278 - 2690 2.00GB (413/0/0) 4202688
Now lets Swap the Swap


First, reinitialize swap submirror.
metainit d21
d21: Concat/Stripe is setup

Add swap to new submirror

\swap -a /dev/md/dsk/d21

View swap

swap -l
swapfile dev swaplo blocks free
/dev/md/dsk/d1 85,1 16 2106416 2106416
/dev/md/dsk/d21 85,21 16 115965680 115965680

Remove the metadevice from swap

swap -d /dev/md/dsk/d1

Verify that previous step worked

swap -l
swapfile dev swaplo blocks free
/dev/md/dsk/d21 85,21 16 115965680 115965680

Clear Metadevice/Mirror

metaclear d1
Mirror is cleared
Clear Metadevice/submirror
metaclear d11
d11: Concat/Stripe is cleared

Format Primary Disk (c1t1d0 in this example)

Select a predefined table

partition> select
0. original
1. my_table
Specify table (enter its number)[0]: 1
View the partition table, and make sure it looks right.
Total disk cylinders available: 14087 + 2 (reserved cylinders)

Part Tag Flag Cylinders Size Blocks
0 root wm 0 - 824 4.00GB (825/0/0) 8395200
1 swap wu 2691 - 14086 55.30GB (11396/0/0) 115965696
2 backup wm 0 - 14086 68.35GB (14087/0/0) 143349312
3 unassigned wm 1032 - 1038 34.78MB (7/0/0) 71232
4 var wm 1039 - 1657 3.00GB (619/0/0) 6298944
5 home wm 1658 - 2070 2.00GB (413/0/0) 4202688
6 stand wm 2071 - 2277 1.00GB (207/0/0) 2106432
7 stand wm 2278 - 2690 2.00GB (413/0/0) 4202688

Label disk
partition> label
Ready to label disk, continue? y

Put things back the way they were.

Reinitialize the swap submirror on the primary disk

metainit d11
d11: Concat/Stripe is setup

Reinitialize Metadevice Mirror

metainit d1
d1: Mirror is setup

Add the metadevice to swap
swap -a /dev/md/dsk/d1

… and verify that it took

swap -l
swapfile dev swaplo blocks free
/dev/md/dsk/d21 85,21 16 115965680 115965680
/dev/md/dsk/d1 85,1 16 115965680 115965680

Remove the submirror that you added to swap in the step above

swap -d /dev/md/dsk/d21

Reattach Submirror d21 to Mirror d1

metattach d1 d21
d1: submirror d21 is attached

Redefine dump device

dumpadm -d swap
Dump content: kernel pages
Dump device: /dev/md/dsk/d1 (swap)
Savecore directory: /var/crash/blahblah
Savecore enabled: yes
