Fedora Installation :: F12 Install: Ramdisk: Incomplete Write?
Nov 18, 2009
So after deciding to upgrade the existing fedora install on my laptop from 11 to 12, I decided to use the preupgrade method. After grappling with the boot space issue by clearing out an old kernel that was deemed safe to remove by the python script on the preconfig wiki page and then using tune2fs, I left the computer to do it's thing, periodically checking back on it. I come back to my computer, and after an apparent restart I see this message spat out at me:
Code:
ramdisk: incomplete write (3537 ! 5123)
write error
kernel panic - not syncing : VFS : unable to mount root fs on unknown block (0,0)
I need this laptop up and running for tomorrow and I would appreciate any help given. I have a Fedora 11 live CD running on the laptop and there seems to be an extra 210 filesystem present with the folders efi, grub, lost+found in there, as well as some config files, elf-memtest86+-400, what seems to be .img file amongst other things. If necessary, I can provide a screenshot.

I am trying to write to a Ramdisk because I suffer from terrible IO speeds on my VPS. It uses openVZ and I run a Centos 5 distro.
So i created my ramdisk with '/bin/mount -t tmpfs -o size=1G,nr_inodes=10k,mode=0775,noatime,nodiratime tmpfs /tmp'
but whenever I try and copy files to it, it just spams me with 'no space left on device even though there is!
Here is the output of df:
/dev/simfs 157286400 6511452 150774948 5% /
none 16441412 4 16441408 1% /dev
tmpfs 5242880 1296 5241584 1% /disk/test
tmpfs 5242880 1296 5241584 1% /disk/test

I installed XFCE on a machine built with the FC 15 LXDE based live CD using yum groupinstall XFCE. I got a usable XFCE session, but after a period of use, some things have gone missing. The windows don't have minimize,resize and close icons on the top bar. The settings selection for "Window Manager Tweaks" doesn't start any program. The programs that are open in the users session are not saved, even though that option is checked. Can this be explained by corruption of a single file somewhere? Or should I re-install XFCE again.

I am trying to boot a ramdisk and am getting the following error:16384 ram0 (driver?)

I tried to install Squeeze on a new laptop. The installation finished and I was able to log in, but a significant number of packages were missing, including network-manager and network-manager-gnome, OpenOffice, and gdebi. Everything under the System | Administration menu except Login Screen was missing. There's probably more missing, too, but I am not sure how to tell.
It happened a few times but with slightly different results (e.g. I think on one of the earlier install attempts, Iceweasel didn't get installed, but it was included in the most recent attempt). I tried installing using 6.0.1's CD 1, and 6.0.0's hybrid Live image on a USB stick (in both cases, the GNOME version). I had used the same USB stick to install Squeeze successfully on another laptop last week (i.e. I successfully got a complete, working install; I made no changes to the USB stick; then tried to install using it on this new laptop, and saw this behavior).
I tried using both the graphical and text installers. At the step asking what packages you want installed (which allows you to auto-install sshd or mail server, for example), each time I made no changes, so the 3 selected default settings (the first option, Desktop Environment, and the last 2 options, laptop and... whatever the other one is, I don't remember) should all have been installed.
I didn't use the net installer, and I ran the installer offline because both laptops require non-free firmware and I couldn't figure out last week how to get the installer to find that firmware (on another USB stick). So once I got to the GNOME desktop the most recent time, I copied the WiFi chip's firmware .deb onto the laptop and did a 'dpkg -i', then did the same thing to get network-manager-gnome and its dependencies installed; and once I connected to our network I started an 'apt-get install gnome' to try to get the entire desktop environment installed (that also installed the programs that show up under System | Administration).
Is there anything important I might still be missing? Is there a list of installed-by-default packages that I could compare against say a 'dpkg -l'? Does this sound like some sort of known issue?

I have updated using zypper from 11.1 to 11.2. Does this process update the boot/menu.lst file with an entry for the new kernel? Didn't for me.
Any rate, that's not really the problem. I have created a new entry in menu.lst to load the new kernel but I don't have a ramdisk image - all I have is a broken link initrd -> initrd-2.6.31.5-0.1-default
Where do I get the image from?

I make it a habit to review the logwatch reports regularly. I have been seeing this one from Anacron lately. I'm not sure exactly when it started, but it has been going on for a while now and started after the F13 to F14 upgrade. I have searched and tried to find out what it means, but have come up empty. This is the report:

Is this something that is just spurious and can be safely ignored? If this isn't, how do I go about fixing it?

I'm trying to complete the porting to RHEL 5 of a commercial application that we've had running on AIX and SCO for decades. It originally ran on dumb-terminals, and even now runs on dumb-terminal emulators that run on Windows. We have thousands of customers, many of whom we'd like to migrate to Linux. We're pretty much done with the port, with the exception of this little glitch we're having with pseudo-ttys...
Our app utilizes pseudo-ttys, such that sub-portions of the application run under a screen manager that provides for screen-switching of multiple instances of the sub-apps on non-GUI terminals, some of which are still running serial. In this regard, it is not unlike the GNU "screen" program. However, it also supports file transfers over serial links using zmodem, and requires the ability to switch in and out of a fully 8-bit transparent mode where the screen switching keyboard commands must be ignored.
On AIX, we're using the BSD TIOCUCNTL (UIOCCMD) capability to send commands from the sub-app to the screen manager. TIOCUCNTL provides custom user ioctls and is an ideal way to solve the problem. It is not implemented on Linux, and the "alternative" of TIOCPKT does not provide arbitrary ioctls so at best we'd have to commandeer some of the existing TIOCPKT ioctls for our own use if that's even possible. TIOCPKT seems like a hack, it apparently was implemented not as a general mechanism but to solve problems specific to rlogin/rlogind.
SCO didn't support TIOCUCNTL either, so years ago we used the SVR5 alternative of putmsg/getmsg. This is a streams-based mechanism of sending control information over streams separate from the data. While RHEL 5 seems to have man pages indicating these commands exist, and in fact you can link programs using them to libc without errors, they are apparently stubbed out and return "function not implemented." This seems to be, according to this Wiki, due to certain Linux factions deeming that streams are "technically inadequate":
Certainly, I would agree that a streams implementation that is incomplete is undoubtedly "technically inadequate."
At the same time, it would appear that the SVR5 method of pseudo-tty is now the recommended implementation, the BSD one being "deprecated" (not to mention, also incomplete on Linux, given TIOCUCNTL is missing):
So here I am trying to figure out how to solve the problem. I have found a library that apparently implements the getmsg/putmsg commands for Linux, called libLiS. However, according to IBM, it has a problem with SELinux:
We've had to disable SELinux for other reasons anyway, so this is not a show stopper for us, and I am actively exploring using it as our solution. However, I've never been exactly crazy about the idea of depending on disabling security features to make something work. But, there's something to be said for the compatibility it would offer for our apps.
However, it occured ot me that we are probably not the first to have this problem, and was wondering if perhaps there is another solution that we should consider.
It has occured to me to use named pipes, but this would be rather ugly--we'd have to maintain a directory full of hundreds of named pipes, probably named after the associated ptys that the sub-apps could use to issue control commands to their screen manager, and the manager would have to monitor these pipes for commands, etc.-- certainly possible, but it seems like it might be re-inventing the wheel a bit, or at the very least, is a somewhat kludgy work-around to the apparent lack of any user-customizable control mechanisms in the pseudo-ttys. And we'd have to support it in addition to the code for the other methods since those platforms aren't going away anytime soon (SCO death-throes notwithstanding).

Once I've booted my Etch install disc, are there some parameters in configuration files I can edit in the ramdisk filesystem that will allow me to install Squeeze instead? Or, even, paramters I can edit to point at the archive.debian.org repository to install Etch?
Why:
I've got a Sun Ultra10 with IDE drives (hard disk and cd drive) on which I previously had Etch installed. I recently tried to upgrade it to Squeeze, botched the upgrade, and formatted the drive. I'm now trying to install Squeeze from scratch.
When I use the Squeeze disc (debian-6.0.0-sparc-xfce+lxde-CD-1.iso), it cannot detect my IDE drives. I also have the disc I originally used to install Etch, way back when. It will boot and detect the drives, but cannot install because Etch is no longer in the repositories.

I just noticed this in my "df" output:
[Code]...
There's an entry in /etc/fstab which mounts this automatically. If I interpret that correctly, that's a 224 mbyte ramdisk that is consuming 224 mbytes of system memory whether or not I use it. Is that correct? If so, will anything break if I unmount it and delete it from /etc/fstab? Do programs typically depend on it? I'd like to reclaim the system memory (low DRAM machine) for other uses.

So I managed to install Debian Jessie on a MSI G70 2PE Apache Pro that came with Windows 8.
First I partitioned some space on the laptop. Then I put on the net install cd for Debian and installed it on UEFI mode. It installed correctly.
Now I'm on Grub and when Debian tries to boot it gets stuck on "Loading initial ramdisk". The cursor under it doesn't even blink. The only way to get out of there is by Ctrl-Alt-Delete. Secure Boot is turned off. Fast boot is also off. If I try to boot on recovery mode gets stuck all the same.
The options on my grub are
Debian GNU/Linux
Advanced options for Debian GNU/Linux
Windows Boot Manager (UEFI on /dev/sda2)
System Setup.
If I choose the Windows option, Windows boots, no problem.
If I choose the edit option for the Debian entry this is what it shows
Code: Select allload_video
insmod gzio
insmod part_gpt
insmod ext2
set root='hd0,gpt6'
if [ x$feature_platform_search_hint = xy ]; then
[Code] ....
What is happening and what should I try to make this work? Could it be a graphics card issue since this computer has a Nvidia Gpu?

Everything is fine until I try to install it into /usr/local (or somewhere in there). The Google Earth Setup keeps telling me that I do not have write permissions on this directory. Question: How do I change the write permissions for this folder? Or should I install the program somewhere else?

I downloaded the oxygen cursors and oxygen cursors extras form the official ubuntu repos using synaptic. I am running gnome in ubuntu lucid with compiz and emerald. I installed them system wide by running
Code: sudo update-alternatives --config x-cursor-theme This means that they are displayed eveywhere. However, there appear to some bits missing from the cursor set. Specifically, the window resize icons and the drag and drop (move) icon. All other icons are displayed correctly. For the missing icons, it seems to fall back to the default ugly black x cursors. Has anybody else seen this, or have I installed these cursors incorrectly? Note I want to do this system wide so I have the same cursor even in my sudoed apps.

Going haywire on a new Centos 5.4 64bit install on vmware esx 4. I should know, but my mind is obviously fucked up today. I get the "distination unreachable", indicating something ICMP related, checked network setup, all looks like usual. Except my routing table lacks the 127.0.0.0 and 0.0.0.0 def. gw entries, as in this working box example:
192.168.9.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.9.1 0.0.0.0 UG 0 0 0 eth0
FWIW, during install, did the usual basic firewall steps, not'n extra added but SSH. Tried with/without iptables, no change; no wonder given the lacky routing table. Sure, I can add what's missing, but I'd like to know why it's missing; i.e. what I missed on basic setup, as I'm going to repeat this with a nof Centos/RHEL installations (replacing SLES).

Using Ubuntu Server 10.04 LTS. I'm new to Ubuntu and testing Rsync. I successfully copied 3TB of data from a Win7 machine to an MDADM Raid5 array. All appears to be fine. Used a Win app for the copy. I then deleted a 250GB folder on the Raid5 array and recopied the data using Rsync. Rsync was executed via a Putty session on a WinXP machine. The source was an eSata attached drive (same drive used for the big 3TB copy) and the destination was the same Raid5 array. That copied just fine. I bit verified it with a Win7 app. Perfect.
I then used the following Rsync script to copy a single 26GB file from that same eSata drive back to (what I intended to be) the Raid5 array:
Code:
neil@ANTECUBSV:/mnt$ rsync -r -a -v -e ssh --delete /mnt/disk1/Test/ /mnt/Test
sending incremental file list
created directory /mnt/Test
./ C_VOL-S300-b001.spf
sent 3020267622 bytes received 34 bytes 50760800.94 bytes/sec
total size is 3019898880 speedup is 1.00
neil@ANTECUBSV:/mnt$ cd raid
Note that only about 3GB copied. No error messages were posted to the putty session. I made a mistake in the Rsync command, creating the Test folder directly in the mount folder rather than the Raid array, as I intended. That is a little strange, yes, but I would not think it would cause a partial copy? The /mnt folder is on my system drive, which had about 34GB available space before the copy, so comfortably would have had 6GB or so after.
The eSata disk is mounted as /mnt/disk1
The Raid5 array is mounted as /mnt/raid
I then recopied the file to the correct intended destination on the Raid5 array, which has about 400GB free space (plenty).
Code:
neil@ANTECUBSV:/mnt/raid$ rsync -r -a -v -e ssh --delete /mnt/disk1/Test/ /mnt/raid/Test
sending incremental file list
./
deleting 2010-07-05 Backyard Birds/Thumbs.db
deleting 2010-07-05 Backyard Birds/
C_VOL-S300-b001.spf
sent 11105775462 bytes received 34 bytes 50366328.78 bytes/sec
total size is 11104419840 speedup is 1.00
neil@ANTECUBSV:/mnt/raid$ df -h
Note that only about 11GB was copied, and this was confirmed with an ls -l command. Now I am correctly copying the file to the Raid array but it is still incomplete. I then copied the file back to the /mnt folder to see if the problem reproduces:
Code:
neil@ANTECUBSV:/mnt/raid$ rsync -r -a -v -e ssh --delete /mnt/disk1/Test/ /mnt/Test
sending incremental file list
created directory /mnt/Test
./
C_VOL-S300-b001.spf
sent 26327927554 bytes received 34 bytes 56558383.65 bytes/sec
total size is 26324713984 speedup is 1.00
neil@ANTECUBSV:/mnt/raid$ cd /mnt/test
This time I got my full 26GB file. Why I might be getting inconsistent results? This is quite troubling of course. I'd also be interested in basic a command line Linux diff app (that does file directory as well as bit level checking) if one is available.

I'm trying to backup an ext3-formatted disk to an external USB disk, also formatted in ext3.rsync repeatedly reports those kind of errors : rsync: recv_generator: failed to stat "<filename>" : Invalid or incomplete multibyte or wide character.Following Google, this is usually related to NTFS-formatted drives but it is not the case here.A lead to the solution could be that the folders and files being backuped are mapped through smbd. My smbd.conf file contains the following lines regarding charsets : #Dos charset = 850#Unix charset = ISO8859-1Since those lines are commented out, I believe this defaults to UTF-8.
