How do you set the Unraid server to be the master browser?

 

I have two machines that are on all the time - the UNRAID server and a Media Server (used to run Windows Media Center 7 and is hooked up to the main tv).

Hang on - I see my server, I even see the shares, when I click on the share it shows no files. I map to server\disk1 I can see all data.

Then sometimes the shares work fine

Then they disappear

Then they reappear

 

Not a DNS resolution issue.

On the "Settings" page in the web-management interface, in the "Identification" section, there is a Yes/No field for "Local Master"

My Network

 

Router

Lynksys wireless N WRT320N firmware  v1.0.03  

 

Router is hooked up to the internet via Cablemodem.

 

Router has a built in 5 port gigabit switch and has a 10 port 10/100 Netgear 10 port switched attached via Cat5 - this switch is the main switch for the house. From this switch a cat 5 runs to a Cisco 8 port 10/100 switch. 2 cat 5 cables connect to the UNRAID server from the switch, other devices such as my main desktop, slingbox etc are hooked up to this router.

 

All this used to work fine - all that has changed is:

1. Windows 7 machines on the network

2. UNRAID server upgraded with 2TB drives

3. UNRAID parity drive had to be moved from motherboard controller to PCI bus based SATA controller - motherboard controller did not recognize the 2TB drive.

4. UNRAID server OS version changes - upgraded from 4.2.1 to all versions since - problem has not resolved.

5. Original upgrade from 4.2.1 was due to Windows 7 error message - too many files open

 

 

Thanks Joe L.

 

I made the change - do I have to do a restart?

 

ps. Now running UNRAID 4.5.6

I honestly don't know how often window's PC poll for who should be the "master browser"  Probably a reboot of the window's PC would do it.

well my personal laptop which is the machine I am on now - is seeing the shares - no reboot on any machine.

 

Shall monitor this and post either way.

 

Appreciate the help - THANK YOU!

Well the shares were there for while - now they are gone again.

 

I have checked with:

1. Windows 7 pc on the same wired network on the same switch as the UNRAID server

2. Windows XP laptop on wireless

3. Windows 7 laptop on wireless

 

All were seeing the shares before.

NOTHING has been changed by me.

All drive shares are still up and running.

 

Anything useful in the log files I shared?

 

PROBLEM CONTINUES.

 

ps. I rebooted the windows 7 laptop and still no shares.

Have you looked in the event log on the Window's 7 PC to see if it offers any clues?

Do these settings have any implication:

 

Disk settings

Default spin down delay:

Force NCQ disabled: Yes

Enable spinup groups: Yes

Tunable (md_num_stripes): 1280 default

Tunable (md_write_limit): 768 default

Tunable (md_sync_window): 288 default

 

oh and by the way the shares are back...

Nothing in the event log I can link to this problem on the windows 7 desktop on wired connection.

 

Its like something is timing out - that should show in the log files from the unraid server but I do not know enough linux to decipher them.

no.

 

1. Is there a linux command I can use to see if a particular service is hanging? like taskmanager - this application is not responding?

 

2. Has no one else ever experienced this problem with UNRAID - I am the onlyone?

 

3. Is there a way for me to delete all the user shares - and recreate them - without loosing the directory structure and data?

 

4. Is there nothing useful in the log files I uploaded?

 

5. Any other ideas on what I can try?

 

Thanks in advance.

Any help?

1. Is there a linux command I can use to see if a particular service is hanging? like taskmanager - this application is not responding?

yes,

ps -ef

will show you all running processes.  You are looking for smbd and nmbd

 

2. Has no one else ever experienced this problem with UNRAID - I am the onlyone?

You are the only one.  It is probably a problem with which PC is the taking on master browser role on your LAN.

3. Is there a way for me to delete all the user shares - and recreate them - without loosing the directory structure and data?

Yes, just reboot the unRAID server.  The user-shares are re-created every time you reboot.

4. Is there nothing useful in the log files I uploaded?

Nothing glaring.

 

5. Any other ideas on what I can try?

 

Thanks in advance.

Thanks Joe.

 

Here's another symptom - when I try to copy a large amount of data say over 1.5gig the process chokes - after a short while of copying windows (7) comes back and complains that the share cannot be reached. But if you copy in increments of about 1gig no problems.

 

Not sure if this is related.

 

It's almost like some buffer or some memory is just not getting released.

Thanks Joe.

This almost sounds like a problem with the NIC.  It might have a slight problem with the driver, or the NIC itself may be marginal in quality (for whatever reason).

 

Try putting an intel PCI GB NIC into the system and disable the onboard NIC.

I tend to agree with the NIC assessment. Weird thing is the problem just manifested it self suddenly - but then it is very old hardware so I shouldn't be surprised.

 

Copying large amount of data onto the server seems to slow it down and prevent further copying as well.

 

Time to upgrade the machine I think.

But hang on if it was the NIC then stopping and starting UNRAID should not fix the problem - and it does - I do not do a complete shutdown of the machine, just a stop start in the unraid console.

What does this setting in the share.cfg file do?

 

 

shareCacheFloor=2000000

I am in the process of ordering new hardware for my main desktop - and will be moving my existing motherboard and CPU to my UNRAID server to update the hardware. But being a problem solver I can not help but want to know/understand what exactly is the cause for this continued failure.

 

The last two - three weeks the unraid server had functioned 100% no loss of shares and heavy use - and then poof stopped. No shares, no disk shares, no console.

 

But this time I saw an error on the screen of the unraid server:

 

reiserfs error device md6 vs-13070 reiserfs_read_locked_inode 10 failure occurred trying to find stat data of 36 377 0x0sd

 

this message was repeated many many times - basically filled the screen

 

Much obliged if someone could help decipher this for me.

Thanks in advance.

I'll try...

 

md6 is affiliated with disk6 in your array.

 

If the message filled your syslog, it would eventually use up all available memory and then the kernel out-of-memory process would start killing off (randomly) process that it though were idle the longest in order to free more memory.  Typically the emhttp web-management console is oone of the first to be killed since it is idle 99.99% of the time.  Then the samba processes tend to be killed off. That stops you from making additional SMB connections.  Eventually, the whole server will become un-responsive.

 

As far as the actual error: odsds are high you have some corruption of the reiser file-system on /dev/md6
