Red Hat / Fedora :: Fiber Channel 4 Terrabyte Mount?
Nov 10, 2010
I need to mount a drive over fiber channel. It's a 4 terabyte drive. We're using a paragon driver to access other volumes on the SAN in a similar way. Works fine. I mount the other volumes as mount -t ufsd /dev/sdd1 /mnt/VolumeName Works fine. This is also an ntfs drive. The error I get when I mount: mount -t ufsd /dev/sdg1 /mnt/VolumeName01 is NTFS-fs error (device sdg1): ntfs_fill_super(): Device has unsupported hardsect_size
Setting up a new Centos 5.5 server with an LSI Logic 7402XP fiber channel HBA card connected by fiber to an enclosure with 28 SATA drives.This is just a bunch of disks.I want to mount them /disk1, /disk2,disk28. No RAID or LVM. After connecting the dsisks and rebooting there are 28 new devices /dev/sdc, /dev/sdd, ...
/dev/sdad. Going to /sys/class/scsi_disk will list all of them. Pick any one and go into device and you can cat the vendor and model and state is "Running." But try parted /dev/sdc and it just quitts. fdisk and mkfs produce errors. Attepting to read or write the device directly with dd fails. The mpt fusion kernel mods are present. I'm pretty sure this hardware is on the suuported list. And I've tried swapping out the card and cables in case of bad hardware. What am I missing to be able to partition and mkfs these disks?

I have a Windows 2003 server with fiber attached volumes (NTFS) that I would like to mount readonly on a linux system to back it up to tape. The fiber device will allow me to present the volume R/W to one host and R/O to another, however, the R/O system doesn't see any of the changes made by the R/W server. In other words, how can I make a readonly volume refresh, scan for changes, or update without un/re-mounting it?
Is the "mount -o --bind" option what I want? From the MAN is doesn't seem right... the option "sync" seems slightly more promising but I think I'm just grasping at straws here. The best I have come up with is a cron job to unmount then mount the volume periodically.
I've been using a WD MyBook terrabyte USB drive for several months with no problem. Several days ago, I used the "safely remove drive" option but then unplugged the cable before the removal process had finished.
Now when I plug the drive in, the WD SmartWave section of the drive will mount. This is additional software for Windows computers that came with the drive and that I don't use. The main drive itself, though, will not mount. The drive doesn't show up on the left side of a navigation window, either.
I can see the drive using Disk Utility. It is located at /dev/sbd. (a) mount this drive or (b) recover its data so I can format it? I'd much prefer (a), of course. Regarding my level of tech savvy: I've been using Ubuntu for a couple years, but I chose Ubuntu because it allows me to use Linux while still remaining relatively ignorant about things, which is my comfort zone.
PC seems to run fine in single channel mode but monitor reports no input in dual channel mode and memtest86+ lists from 1-3 errors per pass in single channel mode. Motherboard (Gigabyte P43T-ES3G) can't be set for the 1.65 volts required by the RAM (2x2 of OCZ3P1333LV4GK PC3 10666). The mobo voltage choices are 1.6 or 1.7 volts. I have tried both and increased the MCH voltage from 1.1 v to 1.2 v, but so far can't get it to run in dual channel mode at all and single channel mode seems to run fine but I still get errors in memtest86+. Also tried optimized Bios settings and loosened memory timings (from 7-7-7-16 to 8-8-8-27 and tRFC 60 to 70) and reset Command Rate from 0 to 2. CPU is Core 2 Quad @ 2.4 Ghz, PSU is rated at 400 watts, Video card is Gigabyte GT220.
I'm trying to crack my wep password just for kicks, but I keep running into the same error. When I try to use airplay-ng for the packet injection, it always gives me the error " wlan0 is on channel -1, but the AP uses channel 6". I've tried setting wlan0 to channel 6 manually, but that doesn't help. I spent a while searching for a solution, but it seemed like each page had a different, usually highly complex solution, that still doesn't work. I have the most recent drivers for my wireless card, and it meets all the requirements. So, is there any solution to this that will actually work?
Thinking about building a new system, with 4GB of DDR3 RAM. I am just wondering, which would you prefer: Dual-channel DDR3 or Quad-channel DDR3? Does one have better speed performance over another? Will one way keep your system cooler?
I have installed 2 fc cards .I have attached FT-SAn to these cards now when i see miltipath -ll output , it shows some path for the multipath can you bfief from where these paths are taking the value . significance of each digit
Need help on how the scsi and multipathing works in Linux. From the docs i have read, i understand that by the use of multipathing we can assign multiple paths to a SAN partition. If there is a problem then one path will failover to other path.However, i am not clear on how linux recognizes the SAN partitions using the multipath drivers. For e.g. I have a HP Proliant server on which we have the following mounts:
Filesystem Size Used Avail Use% Mounted on /dev/cciss/c0d0p3 59G 11G 46G 20% / /dev/cciss/c0d0p1 494M 27M 443M 6% /boot
I'm using wifi "usb card" from airlive with zd1211 driver in Fedora 12 OS. And I cannot access channel 12 and 13. Perhaps for US restrictions. But in EU are allowed. Any idea how to enable them?
iw phy told me the card has 14 channels width but last 3 are disabled.
I tried "iw reg set EU" but "iw reg get" still return me "Country:98"
Also set env. variable COUNTRY=SK and execute crda returns me: Failed to set regulatory domain: -22
in dmesg I can see the regulatory domain is first set to EU but when zd1211 is loaded it is set to US
I had to replace the motherboard, processor, memory on a machine because the old motherboard died. It worked fine under the old board but the new board (Gigabyte 880GA-UD3H) is causing Fedora 11 (and the Fedora 14 Live CD) to fail when initializing an Adaptec AHA-3940UW SCSI adapter.
I was able to display the boot messages and found that the first channel on the adapter is fine, but the second channel causes the boot to hang. The messages are:
aic7xxx 0000:05:04.0: PCI INT A -> GSI 21 (level, low) -> IRQ 21 scsi6 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 7.0 <Adaptec 3940 Ultra SCSI adapter> aic7880: Ultra Wide Channel A, SCSI Id=7, 16/254 SCBs aic7xxx 0000:05:05.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22
Now the file upload feature is working, I have added the correctly indented php file as an attachment on post no: 3. The attached php script will create any missing smart channel files from the equivalent yum repo files. Any new smart channel files will be placed in a /new-smart-channels subdir of the yum repos directory.
Installation Copy the attached php CLI script below to a new file, called create-smart-channels.php. Change the permissions to something like: # chown root:root create-smart-channels.php # chmod 755 create-smart-channels.php
Then place the script in the directory that contains your yum repo files, usually /etc/yum.repos.d/
If you have set any open_basedir restrictions in /etc/php.ini, you will also need to add '/etc/smart/channels/:' to the search paths to allow create-smart-channels.php to read the contents of the /etc/smart/channels/ directory.
Warning: Do not allow php access to the whole of the /etc directory. This could be a security issue. Whatever access restrictions are set with open_basedir (if any), you should override these in your httpd.conf file, to restrict apache's php module to only allow access to php files under your apache's document root. To do this, use something like this in your httpd.conf file:
<Directory /> Options None AllowOverride None Order Deny,Allow Deny from all
# these are the only directories which the apache PHP module can # have access to. This setting overrides the settings in the # global php.ini file, which applies to the CLI version of PHP .....
For some reason the unmentioned former disto, I could not get wireless networking under this configuration and a simple wlan0 interface, in case either cable were to sever it would retain a wireless. The bonding was done for speed, and I believe I can't get faster than mode=4.
i have a skystar 2.6d card.i set everything in Kaffeine and when i search the channels it finds some but when i click on the channel to watch it nothing appears.even in properties of selected channel the frequency is showed up something else. For example the freq of channel Y is 12345 but in the properties of the channel it shows 57329 without any video pid and audio pid.
Its annoying to unmount my flash drive twice.. its not a major problem actually but its kinda annoying , its whenever i plug-in my flash drive.. everything works well except when i need to un-mount it.. I usually unmount it twice using right-click of the mouse, then it mounts itself back, so i have to unmount it again.. Is there any way to control this? How do i setup the auto-mount option for USB flash drives?
I've decided to give PulseAudio a try and since it is working almost without any problems; the only problem I haven't been able to solve (even after some searching through the Internet) is this one:At the moment I've got only 1 mixer channel for output, called Internal Audio Analog Stereo. Now this channel controls both the volume going to the integrated speakers of my notebook and to headphones as well. What I was trying to do is to separate those channels in the same way how ALSA does it without PulseAuio.ALSA Situation without PulseAudio:~ Master ~ Speaker ~ PCM ~ FrontALSA with PulseAudio: ~ Master (controls everything)I was hoping to use the Master and Speaker in PulseAudio. My attempts were unsuccessfulHere are some tech data about my distro, ALSA, PulseAudio and sound card:Linux Distro info + PulseAudio USE Flags:
I have a 4.1 surround setup that the computer sees a 4 channel setup (stuff going to subwoofer is split out in hardware so all the computer sees is the front and rear l/r channels).
All well and good, but phonon isn't giving me an option to set my output to 4 channels, only stereo (which means my rear speakers are useless) or 5.1 (which makes me fear losing channels if I play anything with actual surround sound).
I have a creative sound card (ca106 driver) detected and working. This is a 5.1 capable soundcard and i also have 5.1 speaker system. The sound card works, however, the problem is that only the front speakers are working. I have checked vlc settings, in which front speakers, centre and rear are seen as different devices.
found one other post with this same issue, and the final reply was "I give up"...I got a fresh 9.1 install. I just want to record some audio, but it's only recording on one channel, the left channel.I tried audacity and sound recorder. checked the sound preferences, Hardware set to Analog Stereo Duplex. In audacity Preferences > Devices > Recording, 2 (Stereo) is selected.When recording in audacity the output meter for the left channel shows activity while the right channel looks like it goes up a little bit but doesn't peak like the left channel. I hear fuzziness in the right but all the sound is in the left
I have a fresh install of Ubuntu 10.04 and I cant seem get the sound working properly. I have a checked to make sure that nothing is muted, and I do have sound over the rear channel when I change the wiring on the physical machine. However, I get no sound over the headphone channel. I also changed the conf for pulseaudio to have a default of 2 sound channels. In addition the sound works fine in my Fedora 13 and Win 7 installs, this is a triple boot machine .
When I'm on Vista (I dual boot by the way) I see that my hard drive is about 13Gb smaller than it used to be, but I have no access to Ubuntu's files. However, when I am on Ubuntu I have access to a drive (is it a drive?) I believe is called OS and when mounted it lets me access all of Vista's documents.
Also I do not understand the difference between /home, OS, and System Files (It might be named something else, but the icon looks like a hard drive I believe).
I realize all this is pretty vague, but do you know a way to block this connection? I feel like Harry Potter looking into Voldemort's mind (lol).
PS Despite the Voldemort reference I am not a MS Windows hater.
I have a netbook running squeeze + lxde. Every time I boot, I have to open alsamixer and turn on my speaker channel. Master and PCM are both enabled and at 100%, as is everything relating to the mic. Speaker just refuses to work with me though.
Recently I have been trying out quassel, while its a good IRC client security-wise it does fail in one crucial aspect which is the GUI which needs a lot of polish. A
Anyways, this is my setup. I am usually on two networks irc.freenode.org and irc.oftc.net and have number of channels which I want to autojoin and also later be able to add channels to the list.
Let's say the chat list name is DebianIRC (which is the default chat list). Does anybody know how can I do both/either of the things. So things to be done are :-
a. As far as I understand quassel ONLY lets one chat list be from the first network. I haven't been able to figure out how to add the second networks channels to the list while doing the initial setup.
b. How to later add channels from either or even a new networks (quassel calls IRC domain servers such as irc.freenode.org/irc.oftc.net as networks) to an existing list . For an example if the list is named as DebianIRC.
c. Also does somebody know where the logs are kept and any tricks/tips people do with the logs. By default I want logging on and on some channels more intensive logging than others.
I have the issue that the right channel is nearly to be muted (very low gain, high distortions).
This is my scenario now: cat /proc/version Linux version 2.6.30-spalsh (2.6.30) (root@angel3) (gcc version 4.3.4 (Debian 4.3.4-6) ) #1 SMP Mon Dec 14 22:03:13 CET 2009
openSuse v11.1linux 2.6.27.39-0.2-default x86_64realtek acl1200 codecSound for various devices is at best erratic. It is hit or miss whether sound emits at any given time.Sometimes Flash player (in Firefox) has sound, sometimes not.Sometimes mplayer has sound, sometimes not. (A workaround for mplayer is to install the ALSA dev package and rebuild mplayer. It still fails on the default channel but succeeds on ALSA.)The message in mplayer is
Code: [AO OSS] audio_setup: Can't open audio device /dev/dsp: Device or resource busy "fuser /dev/dsp" returns nothing.
