similar to: Asterisk on USB Flash?

Hello! I'm using a CompactFlash as storage device. Since those CF cards only have limited write cycles (CF does wear-levelling by itself, but you don't want to write too many timet so the card) i was wondering by what a factor the journaling of ext3 increases the write accesses to the CompactFlash compared to ext2. Thanks a lot already for your help! Sincerely Chris Braun

I've been thinking of making a (mostly) solid-state asterisk pbx. Take either centos or some other distro, cut it down to bare minimum and put asterisk + AMP on. Something that could be put onto a usb2.0 flash stick, bootable. Modern flash devices (usb, compactflash) have builtin wear leveling management and will last longer than you think:

I am looking at ways to harden my asterisk install to prevent computer related issues from happening. I am concerned about about disk write cache. That seems to be a major source of hard drive corruption on power failure. Hard Drive corruption is simply unacceptable for the 99.999% uptime requirements of my Asterisk install that needs to be as reliable as a proprietary PBX. Of course I will be

I need to calculate some metrics such as Mean Time Between Failure (MTBF), etc (see http://www.cs.sandia.gov/~jrstear/ras for a more complete list). I have observations like start end state 1 2005-11-11 09:05:00 2005-11-11 12:20:00 Scheduled Downtime 2 2005-11-12 13:42:00 2005-11-12 14:45:00 Unscheduled Downtime where each row describes

Hello, I have a question about ext3 write activity. I am considering using an ext3 fs on a CompactFlash disk for my data-logging application (power can disapear anytime). The quantity & frequency of the data logged itself is not a problem at all considering flash wear. But I'm a bit worried about the kernel/ext3 doing regular writes by itself even when there are no userspace writes.

Hi folks, I'm trying to make a CompactFlash bootable with SYSLINUX. The hard part is that I'm trying to run SYSLINUX on Windows 2000 and am attempting to write to the compactflash that's plugged in via a USB reader/writer. Its not working -- Windows complains about the 16-bit subsystem wanting direct access to the drive. So then is the problem SYSLINUX fighting with Windows or

SYSLINUX 2.10 2004-06-18 That is all I get when I boot my system off a CompactFlash card in an IDE adapter, no matter how long I wait. What debugging steps are recommended? I'm willing to get down and dirty with assembler, and I'd appreciate suggestions of what to suspect and where to start. Details: This is a Crucial 128MB CompactFlash card in a non-hot-swap CF-IDE adapter which

Hi folks, I hit the syslinux homepage for the first time in a while. The stuff just works, so there's no reason to come to the website, eh? :) Anyway, the first line is "The SYSLINUX Project covers lightweight bootloaders for floppy media (SYSLINUX)", and I think that this needs to be expanded a bit. I use SYSLINUX on CompactFlash, and it works great because together with

Hi folks, I'm having problems now with the Win32 syslinux in the 2.0.6 release when using it on various CompactFlash drives. These drives end up going into a Geode-based PC board with a built in CF slot. Now, before I run SYSLINUX.EXE on them, they are 32MB with a Toshiba part number showing up when the PC boots. They show up on as the Secondary Master. After I run SYSLINUX.EXE, they stay

We are implementing a ZFS storage server (NAS) to replace a NetApp box. I have a Sun server with two dual Ultra320 PCIX cards connected to 4 shelves of 12 500GB disks each, yielding a total of 24TB of raw storage. I''m kicking around the different ways to carve this space up, balancing storage space with data integrity. The layout that I have come to think is the best for me is to

Hi All, On several of my servers I seem to have a high rate of server crashes do to file system errors. So I have some questions related to this: Is there any Mean Time Between Failure ( MTBF) data for the ext3 file-system? Does increased partition size cause a higher risk of the partition being corrupted? If so, is there any data on the ratio between partition size and the likely hood of

I understand that ZFS provides fault data, via the zpool status command, that would (probably ??) allow a knowledgeable[0] zfs admin to determine (manually) when a zfs hardware element (today that''s usually called a "disk drive") might need "maintainence" or might need to be replaced. And there are sufficient features/facilities available in the current (b36+) release

I'm working on a project involving reliability values (known failure rates) for a system with approximately 700 components with a set cconfiguration. I'm looking to compute a "parts-count" MTBF (mean time between failures) for the system. (See also MIL-HDBK-217) Is there anything in R that can help me with this? Thanks, Eric Jennings QA Technical Assistant Crane

Hello For those SOHO customers (ie. at most, a couple of POTS/ISDN connections and simultaneous SIP calls) who'd rather not use a big, noisy PC to run Asterisk, I'd like to offer an alternative that has the following features: - not old hardware sold on eBay, ie. it must be up-to-date hardware sold by a company currently in business - compact, silent - has room for a 2.5" hard-disk,

Can anyone recommend an enterprise-class monitoring system for both Linux and Windows servers? Here are my requirements: SNMP trap collection, ability to import custom MIBs isup/isdown monitoring of ports and daemons Server health monitors (CPU, Disk, Memory, etc) SLA reporting with nice graphs Pager/Email/SMS alerts with groups, filters and escalations Built-in MTBF and MTTR reporting Robust

Hello, We use all SCSI PCI card hardware RAIDs on all 4 of our production Asterisk servers. They all have Digium quad T1 cards and they all have from 2 to 4 T1s hooked up to them. We have had no noticable problems with dropped calls/poor quality. What are you looking to do with this system? what kind of traffic will be going through these 4 T1s?

Hi all, I have a machine running Ubuntu that I run Asterisk 1.4.x on and it runs very well. On that machine I have a SIP phone. I have configured a netgear wgt634u with asterisk and a SIP phone and linked the two systems together via IAX. Audio from Ubuntu to netgear is not bad, audio from netgear to ubuntu is unintelligible. Any clues as to whether this will work? Configuration suggestions?

Hi! If you are trying to syslinux floppies or CompactFlash cards from within Windows in a command prompt, here is a hint: run 'syslinux.EXE drive_letter:' instead of 'syslinux drive_letter:' I banged my head yesterday with it... ;) p.s. yes this also works with an USB adaptor Luis Correia PGP Fingerprint: BC44 D7DA 5A17 F92A CA21 9ABE DFF0 3540 2322 21F6 Key Server:

Just an FYI to anyone out there who will be attending Astricon and who would like to play around with embedded Asterisk on the Netgear WGT634U platform. If you want to "bring your own" to the show, I'll be bringing all the appropriate stuff to flash them there with my latest openWGT/Asterisk build. They are available from www.justdeals.com, refurbs, for $44.95 delivered.
