[new] fuse (= Filesystem in Userspace )

This seems to be main dependency for gmailfs and it also looks like very useful for other usage.

some tipps for your work:
- if you post PKGBUILD's in the forum, use [code] instead of
, so that the code is formated in monospace chars (easier to read)
- you can use make without the absolute path, as it is (should be always) in the PATH ("make" instead of "/usr/bin/make" is ok)
- no depends=() ? (i don't know this software, but it maybe needs other software to link or use while running)
hope this helps

50.5 Fuser Error with new fuser installed

Our HP Color LazerJet CP6015 Printer stopped working because of a "50.5 Fuser Error". We ordering and installing a new Image Fuser Kit (220v) but it still shows the same error message. Anyone have any ideas how to fix the problem?

New install - Filesystem check failed

I did a new installation of Arch today, and in a random fit of thrillseeking I used syslinux instead of grub for the bootloader. The installation said it was successful, but after restarting Arch failed to boot. The error was in the filesystem check.
/dev/sda5 is mounted. e2fsck: Cannot continue, aborting.
/dev/sda5 is where /usr is mounted.
Also, it complained that / is mounted read-only.
First question is, how is /usr already mounted? I searched the forums and the most promising thing I found involved mkinitcpio; apparently it tries to take a shortcut and mount /usr early and somehow this happens before the filesystems are fscked. However, I added the shutdown and fsck hooks to /etc/mkinitcpio.conf which are supposed to fix this (https://wiki.archlinux.org/index.php/Mk … _partition), and nothing changed. So I'm out of ideas.
Second, why is / read-only? fstab only has the 'defaults' option listed for /. syslinux.cfg had the line 'APPEND root=/dev/sda2 ro' so I figured it was probably read-only because of that, but I tried booting both with the ro gone and with it changed to rw, but nothing changed there either, it still gives the message that / is mounted read-only.
My first inclination was just to disable the filesystem check in fstab, but that seemed like a cheap workaround. I'd really like to understand what the problem is.

No, I didn't realize I had to but that makes sense. Do I use the ABS, like this: https://wiki.archlinux.org/index.php/Ke … ild_System ? Do I need to do anything special to enable the hooks?

Were you able to resolve this issue? I have the same machine -- V245, Solaris 10 -- which is exhibiting the same behaviour.

I just put a new fuser kit into my copier (5550 series). now, when i print the sheet is pink!

An hp5550 series laserjet printer was just donated to our office. It needed a fuser kit and I just replaced it. Now the sheets are pink when copies are made. What's going on?

Can you provide more information regarding the sheet being pink?
For example:
If you print a single page document with a small amount of color, when the page comes out of the printer it has a pink hue in all areas that are supposed to be white.
If I understand correctly, what you are seeing is not related to changing the fuser. There are a couple of things that you can try to help reduce a pink hue which is also called Background Color:
This web-site references some Print Quality Troubleshooting tips:
http://h20584.www2.hp.com/hpgt/guides/select?lang=en&cc=us&prodTypeId=18972&prodSeriesId=409994
One of the sections within that is regarding troublshooting image formation issues:
http://h20584.www2.hp.com/hpgt/content/cdoc?docId=emr_na-c00230735&lang=en&cc=US&interviewId=b555952...
One easy thing to try is Calibrating the Printer.
In the user manual:
http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c00134099/c00134099.pdf
Search for: "Calibrating The Printer". I would recommend you do a Full Calibration.
I would also recommend that you print a "Supplies Status Page" by entering the menus, selecting "Information" then select "Print Supplies Status Page". Check the status of the Magenta Print Cartridge and the Image Transfer Kit. Given that you had to replace your Fuser Kit, I would expect that the Image Transfer Kit may be getting to the point where it will need to be replaced.
You can find information regarding "HP Color LaserJet Printers - How to Determine if a Cartridge is at the End of its Designed Cartridge Life" at the following like:

Resets for new fuser and transfer units

We have an HP laserjet 4500N on which I changed the transfer unit, the fuser and the drum. After I turned the printer back on, it showed only the drum life to have been reset to 100%, the fuser and transfer units stayed at the 54% and 35% values that were on before the change. I tried to go to the Resets Menu to reset these two values to 100% but the only options I get are Reset Memory or Reset Factory Settings. How can I do correct this?
Thanks

If anyone else is having this issue I found this info on another site:

FUSE Preprocessing Filesystem

EDIT: Updated code, does everything I need it to for now, still maybe a little unclean, but much better than it was.
A while ago I was thinking up ways to pre-process files such as .Xdefaults when they were read, to allow per machine configs and other such things (I think it turns out that Xdefaults actually supports this anyway), and I thought the coolest way to do this would be to use a FUSE filesystem.
Originally I was going to use the standard cpp program to handle the processing, but I've changed this to use gpp for the time being since it seems to work better for this kind of thing. You can have files with stuff like
#if 0
Not going to be printed
#else
This is printed
#exec date
#endif
Compile with
gcc -o prepfs prepfs.c -lfuse -D_FILE_OFFSET_BITS=64 -DFUSE_USE_VERSION=26
Run with
./prepfs mountpoint -b basedir -pp preprocessor (eg, gpp -x "%s")
Your mountpoint will simply mirror whatever basedir is set to, but run all files through the preprocessor before outputting them.

Fuse 1.3

i'm trying to make a package for fuse (filesystem in userspace) but i'm having troubles compiling it. here's my preliminary PKGBUILD

i believe it has to do with my kernel. i'm going to test another kernel, but it will take me some time because i have to apply a reiser4 patch, or i might try the livecd. either way, if someone could test this in the meantime, it would be much appreciated.

i've been unable to get a proper reiser4 patch that works and i'm also having troubles downloading a working version of the amlug live cd. has anyone else tried to compile fuse? it would be much appreciated if someone would just try to makepkg the PKGBUILD, and report whether or not it compiles. thanx!

[Solved] Error compiling kernel 2.6.36.2 patched with MOSIX

Hi, I'm a new user in this forum!
I'm trying to compile manually the kernel version with MOSIX-2.29.0.1 for computer clustering. But When I try to compile it with make command there is an error:
In file included from arch/x86/kernel/signal.c:17:0:

I have launched make menuconfig and I have configured the kernel in this way:
Configure the following option:

But make sure that the following is NOT CONFIGURED:
CONFIG_HEADERS_CHECK"
'Kernel hacking' ---> 'Run 'make headers_check' when building vmlinux'
What is the problem?

I've solved the issue, infact there was a problem with the patch. Now I am able to compile the kernel.
Thanks anyway!

Best use of 24GB SSD ExpressCard? ln? JFFS2 or YAFFS? MacFUSE/Fuse4X?

Ok, so I just got a 24GB SSD ExpressCard ("Wintec FileMate SolidGO" MLC flash drive; Max. Sustained Sequential Read: 115 MB/s & Write: 65 MB/s. ) for my MacBook Pro (MB133LL/A).
I'm hesitant to put the whole OS on it, because I've read that many small writes to the disk are slow and hazardous to the life of SSDs. Also trying to evaluate the pros and cons of having /tmp and/or /var (including /var/vm) on the SSD... I guess my frequently used apps are the most important thing to have on the SSD.
I would guess that if I set up the appropriate symbolic links using ln(1), the OS, apps, user homes and data will work fine spread out over 2 disks, but perhaps there are some gotchas I'm not aware of, or lessons someone's learned by trying this before me...
Wear leveling helps, and, well the Macs sold with SSDs work... and this SSD comes with a 2 year warranty, so maybe I shouldn't worry... I think this SSD doesn't have TRIM support,
There are detailed FAQs and product specs on Wintec's site, but at least some of the info is wrong, so I'm here seeking other opinions on how best to use it. For example, I have no trouble sleeping and waking it and do so often; I didn't have to enable hibernate mode. The specs suggest that booting off the SSD is a good idea, but the troubeshooting/FAQ don't seem to agree with that at all.
What would be fantastic is if I could set up the computer to work like the Seagate Momentus XT 500 GB 2.5 Inch Solid State Hybrid Drive - in other words, the computer would figure out what files were good candidates for caching on the SSD, I wasn't able to find any software that does that, but I'm guessing it's something that could be developed using FUSE(Filesystem in Userspace) implementation such as Fuse4X. It would keep track of accesses and use the SSD for files that were read often, and other optimizations that flash filesystems like JFFS2 and YAFFS have.

I saw someone post somewhere that things had worked fine for them doing this using symbolic links, so I tried that. It was not a good experience. Most of the apps would run, but the Dock would treat them as different apps, as would Little Snitch. I want to have a more stable setup - one that will keep working (after a reboot) if I have to remove the SSD to use another ExpressCard (like for eSATA) or to save battery or because it's failed.
I logged the output of df -h as well as of mount while a bootable 10.7 Lion DVD was running, which looks like a good method to copy, though I'm not sure what the OS was doing to make it so; IIRC there was no fstab file. Here are the output logs:

It's good to see that there's a way to do it that is likely to work well, as Apple uses it.
Bluehz' comments I noted above are from 2003, but are still more impressive/thorough than anything recent I've seen! BlueHz's post incudes a link to good scripts for handling mount points for swap and applications (of Oct 11, '02 vintage • Contributed by: Numbski) that I'm planning to use/adapt.

[S]bad perf b/c (lack of fine-tuning)/(wrong governor)/(redundancy)?

its strange that the cpu has only 800MHz during the bench.
my ondemand threshold: 95
does the bench cause less then 95%?

This on a 3x AMD AthlonII X3 450, modules powernow_k8 and cpufreq_ondemand.
Stepping is 800-2000-2500-3200. Threshold is the default 95%.
I don't think hardinfo is reporting cpu frequency correctly.
Aha. Check out this bug from the hardinfo site:
http://bugs.hardinfo.org/showreport.php?bugid=48
This is a known bug. If you're using cpufreq with the ondemand governor, then the tests will be performed at 3GHz on your machine, as they're quite CPU intensive and the governor will automatically pump out more juice to the CPU.
However, HardInfo only measures the CPU speed once, and that's the speed it displays on the benchmark window.
Oh thank you for the answer, good Sir!
Can you answer the 3rd question?: do you really need laptopmodetools, acpi, cpufreq & acpid? or could i deinst one of them?

Oracle database reorganization (moving datafiles to new filesystems)

Hi All,
We are planning to perform a database reorganization (moving datafiles to new filesystems) in our Production environment using SAPDBA.
We had noticed in our recent performance reports that few datafiles in some of the SAPDATAxx filesystems are having higher I/O contention and are putting heavy load on those filesystems resulting in poor performance. So, we had identified the datafiles and planning to move them to new SAPDATA filesystems (uniformly distribute the datafiles to stabilize the I/O). Below are the version information.
SAP: 3.0F
Oracle: 9.2.0.8
OS: HP-UX 11.23
SAPDBA: 6.20
I'm going through SAP notes and Oracle documentation on this.Can you please share your experiences if similar activity was carried out by any of you and the documents relating to this.
Your inputs on this is very much appreciated.
Thanks,
Vasu

If your goal is just to make use of new storage, it is fairly straightforward and quick to move the datafiles as others mentioned. However, moving the datafile will NOT reorganize tables/tablespaces.
You can optionally reorg tables/tablespaces in addition to the move of datafiles. This generally saves space and helps performance. If you decide to reorg, I would suggest you move the datafiles to faster storage then reorg (since reorg itself is highly IO intensive).
Some points to consider:
- perform the reorg when business use is least
- perform online reorg where possible
- online reorg creates temporary snaps, typically in the users default tablespace, make sure it has sufficient space
- start with small tables/tablespaces first to get throughput estimate and also estimate of reduction in size
- estimate the size of target tablespace (how small it is going to be compared to source) and build the target tablespace smaller to avoid wasting space
- watch the space usage of the target tablespace when the reorg is running
- if you are reorging individual tables, make sure the indexes are rebuilt
Hope this helps.

Shan

How to Format and Label a bootable 20G file-as-a-filesystem?

I'm trying to create a bootable 20G file that has a UFS filesystem.
I'm starting with a bootable Compact Flash (CF) that's 32G, has a UFS file system, and I'd like to "remaster" the 32G CF into a 20G file, then create bootable CF's with "dd" from the 20G file on a Windows "Mastering" machine.
Here's what I've tried:
Create a 20G file:
dd if=/dev/zero of=/export/home/20G bs=1024k count=20000
Add file as a block device
lofiadm -a /export/home/20G
Create a UFS filesystem on the new block device
newfs /dev/lofi/1
Create a new mountpoint for the 20G filesystem
mkdir /export/home/mnt
Install UFS bootblock on the new 20G file system
installboot /usr/platform/sun4v/lib/fs/ufs/bootblk /dev/rlofi/1
Mount the new filesystem
mount /dev/lofi/1 /export/home/mnt
Copy all files from the known good bootable CF to the new 20G filesystem
cd /rmdisk/cf
find . | cpio -pudmv /export/home/mnt
Compare disk usage between source and target
cd /export/home/mnt
du -sk
cd /rmdisk/cf
du -sk
Unmount the 20G filesystem
cd /
umount /export/home/mnt
Remove the 20G loopback filesystem block device
lofiadm -d /dev/lofi/1
Copy the 20G file to a Windows media duplication PC using SFTP.
Copy the 20G file to a new blank CF on the Windows machine using dd for Windows.
dd if=C:\20G of=\\.\Voume{<VOL_NUM>}
Attempt to boot the CF in a Sun CP3260 (sparc)
boot cf
Where the devalias cf is the hardware path to the CF...
Which returns:
Bad magic number in disk label
Can't open disk label package.
Error: boot-read failed.
Can't open boot device.
Any ideas?
Format?
fmthard?
This is a file so it doesn't show up with the format command...

Extend root filesystem

Hi,
i had installed oracle10gR2 on rhel5......in the installation prerequiste i have failed to give enough space for root partition.
At the installation process oracle give the error not enough tmp spaces in root.i want increase this root partition without reinstallation of rhel5.
Please anyone help me how to increase the root size in rhel5
Regards,
S.Mugunthan.

I recommend you to post your question on a Redhat Linux Forum like http://www.linuxquestions.org/questions/red-hat-31/
In my opinion however, the fasted way is - if you have some unformatted diskspace left - to create a new /tmp filesystem and mount that instead of using the root partition /tmp
Remember to erase the current contents on /tmp before mounting. Otherwise space will not be release to the root file system

Viewing .doc/.docx files on new iMac

Hello folks,
I have a new iMac running 10.9.4. I don't seem to be able to open .doc or .docx files in either the new Pages (5.2) or Pages '09, which I've installed. Pages '09 can view both file types quite happily on my old iMac (10.7.5) so I'm a bit mystified.
Can anybody help? Not being able to open these files is a real problem ...
thanks in advance.

Are these Word documents native to your new iMac filesystem, or are they resting on a Google, Dropbox, or other attached storage solution?
What error message is generated when you attempt to open a random Word document in Pages v5.2? Pages ’09? Preview? TextEdit? Do any of these applications just hang attempting to open the Word document?
What other applications that may open Word documents have you installed, if any?
If you single-click to select a random Word document, then press the Spacebar, what default application does Quick Look offer to use?
