Hi, i try to create a openWRT Samba 4.3 package and stumbled across the fact that samba 4.3 will create those message socks inside the private-dir. That results in creating entries inside /etc/samba/msg.sock. On openWRT /var is a tempFS in ram, so anything there is not a problem regarding nvram and wear leveling. Yet the root uses a jffs2 overlay. So while those message socks have no size, jffs2

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:

Size/Speed/write cycles have gone way up, price has gone way down. More common than CompactFlash and no need for an adapter. So is it feasible to run an Asterisk server on something like this? With a MTBF of 1million write cycles coupled with dynamic wear management on a 4Gig USB drive, lifetime is a non-issue. Just wondering how well it works, if it works.

Hi All, I m a novice developer of Linux applications. Recently I faced a file system corruption. (I guess) I have a Kernel 2.4.7-10 with ext3 file system in compact flash. The system was up for 3 months and was running with average load conditions. One fine day, it just started sending kernel messages on the serial console. The message was like this. EXT3-fs error (device ide0(3,2)):

Well, now that I''ve figured out that network booting XCP is not really going to be feasible, I''m moving on to my next option: flash media installation. The systems that I purchased have SDHC slots on them, so I figured I''d attempt to install XCP to one of these cards. I had already read that there''s a minimum disk size in the installer (apparently 12 GB in

Hi We have a number offices accommodating 4-6 people each hence it is very important for PBX to be fanless and silent. We have been looking at using IDE flash disks also called DOM. The performance tests we have done so far satisfy our requirements, however we are concerned with DOM durability. We have installed debian and vanilla asterisk on 1GB DOM. All seems to work fine at the moment however

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! With 3.2-rc4 (probably earlier), Ext4 seems to remember what areas it trimmed: merkaba:~> fstrim -v /boot /boot: 224657408 bytes were trimmed merkaba:~> fstrim -v /boot /boot: 0 bytes were trimmed But BTRFS does not: merkaba:~> fstrim -v / /: 4431613952 bytes were trimmed merkaba:~> fstrim -v / /: 4341846016 bytes were trimmed Is it planned to add this feature to BTRFS

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

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

I''m looking to try BTRFS on a SSD, and I would like to know what SSD optimizations it applies. Is there a comprehensive list of what ssd mount option does? How are the blocks and metadata arranged? Are there options available comparable to ext2/ext3 to help reduce wear and improve performance? Specifically, on ext2 (journal means more writes, so I don''t use ext3 on SSDs,

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,

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:

Hi, I don''t know if it''s already been discussed here, but while thinking about using the OCZ Vertex 2 Pro SSD (which according to spec page has supercaps built in) as a shared slog and L2ARC device it stroke me that this might not be a such a good idea. Because this SSD is MLC based, write cycles are an issue here, though I can''t find any number in their spec. Why do I

Hello I think syslinux is great and just downloaded 2.00 and will start using it in a couple of days. 1. We use an IDE<->compactflash-adapter in our target-system. We use a USB-compact-flash reader/writer(SanDisk/ImageMate) on our linux-host to write the flash. It appears in the Linux-system as '/dev/sda', and we can use syslinux and mount for copying kernel, syslinux.cfg and our

Hi there, Is there a utility to create an EXT3 file system image from directories? Just like the mkfs.jffs2 which creates a JFFS2 file system image from directories? The "mke2fs -j" only creates the bare bone file system, what I want is to build an image with pre-built content. Thanks, Debbie
