Looking for a life-save LVM Guru

Dear All,

I am in desperate need for LVM data rescue for my server.
I have an VG call vg_hosting consisting of 4 PVs each contained in a
separate hard drive (/dev/sda1, /dev/sdb1, /dev/sdc1, and /dev/sdd1).
And this LV: lv_home was created to use all the space of the 4 PVs.

Right now, the third hard drive is damaged; and therefore the third PV
(/dev/sdc1) cannot be accessed anymore. I would like to recover whatever
left in the other 3 PVs (/dev/sda1, /dev/sdb1, and /dev/sdd1).

I have tried with the following:

1. Removing the broken PV:

# vgreduce --force vg_hosting /dev/sdc1
  Physical volume "/dev/sdc1" still in use

# pvmove /dev/sdc1
  No extents available for allocation

2. Replacing the broken PV:

I was able to create a new PV and restore the VG Config/meta data:

# pvcreate --restorefile ... --uuid ... /dev/sdc1
# vgcfgrestore --file ... vg_hosting

However, vgchange would give this error:

Leaping from F18 -> F21


Greetings,

I decided to begin making the leap from F18 to F21. My reluctance in 
upgrading with each new release was due to all of the problems that were 
reported with upgrades, and not wanting to go through a dependency upgrade 
ordeal.

Now with F18 firmly EOL'd and enough packages showing their age and 
demanding upgrades, I've begun making the switch.

I have three machines that run Fedora: two laptops, one of which is an 
i686 and the other a dual-core, and a desktop.

I've started w/ the i686, the least used, and essentially a backup. The 
strategy is to simply leave the /home partition alone, and to do a fresh 
install, reformating the other partitions. (I used the Fedora 21 
Workstation Live i686 disc). Having a list of those RPMs that were 
installed under F18, I'll work my way back to something that I was using 
before.

I did that, but when the machine responded and rebooted, and then I tried 
to login through the GUI to a gnome desktop, the result was unusable.

No problem: <ctrl+alt>+F2 and I have a character-based screen, and I can 
log in.

From there, I did a
yum groupinstall "Xfce Desktop"

Does the game Quadrapassel work fine under nVidia proprietary drivers?

Dear All,

Apparently, not, but could you please confirm that?

Thanks in advance,

graphical interfaces for just **using** MySql/MariaDB?

Greetings,

I am looking for a FOSS graphical interface to ONLY USE,
NOT manage, an already existing MySql or Maria DB database.

In other words, I only need a decent GUI that, with as
little setup as possible, lets me

choose a table in a database
find a record in it
create or modify records in one USABLE form

by usable I mean, at least

put one, max 3/4 field per row, ie fit all in the screen,
instead of showing one row with all the fields, which is 5 times larger
than the screen, thus making me waste a lot of
time to go over it

present all fields that are defined as ENUM as dropdown
menus of all the possible entries

I **KNOW** that Open/Libreoffice can do this, in theory. but in 
practice, for some
reason making them talk to a mysql/mariadb database still never
works painlessly on Fedora, not in my experience anyway

I'd even be happy (even happier, in fact) with a LAMP, in-browser
interface for this, instead of a native desktop client. But I could
not find FOSS php classes/packages that could do the above AND would

problem playing video DVD

Rented a DVD movie (the 3rd in the series Atlas Shrugged).
It would not play with any media player (such as smplayer, vlc, Dragon 
Player, xine, totem, ... etc)

No errors in /var/log/messages.

I told the vendor, and they stuck it into a machine the "tests" it for 
playability.
It took 5 seconds and it declared it playable :) :)  Whatever ....
The surface seemed OK on visual inspection.
So, what could have gone wrong?
Anyone have this problem?

how to set a wakealarm in F20

I would like to set a wakealarm so that my computer will boot up at a 
certain time.
In researching this, all I have found includes altering the 
/etc/rc.d/init.d/halt, which is present if F19 but not in F20.
I have not been able to find anything in systemd about doing this.

Has any one been able to do this. Any pointers in where to look for 
information.

Thanks, David

Qt 4.x -- Qt 5.x -- qtgrace -- segfault

Hi,

I've tried to build and run qtgrace on fedora 20 and it almost always 
segfaults.  The only time it worked was within a remote desktop running 
in x2go.  I have attempted with both Qt 4.x and 5.x from the fedora repo.

qtgrace
http://qtgrace.sourceforge.net/

I tried this posted solution but it still failed on Gnome, LXDE and 
Cinnamon.  It also did not work in the x2go session.
http://sourceforge.net/p/qtgrace/discussion/1358966/thread/838fa2a4/#2e35

There are a number of similar questions found on the software site help 
and Discussion pages.

Any advice to fix this is appreciated.

If a Qt developer can troubleshoot and also advise the developer on 
creating a fedora/centos rpm this would be great.

Thank you,

Re: computer boot (some times) in emergency mode.

Hi,

The message that I get, when the problem come, are (approximately):


========================
Welcome to emergency mode! after logging in , type "journalctl -xb" to view system log .......

SError: {RecovRecovCom PHYRdyChg CommWake 10B8B DevExch }

failed commend : READ DMA



Please don't trim the messages to tidy them, include the entire thing, or post the rdsosreport.txt if one was generated.

Statistically speaking, the errors you post are probably due to a failed read on a critical sector that the system simply can't proceed without reading, so it waits for the drive to recover, and hits the kernel SCSI command timer limit which is 30 seconds. 

If that's true, you might be able to fix the problem by booting with parameter rd.break=cmdline which gets you to a command line before anything is mounted (not even read only). And then do:
# echo 120 > /sys/block/sda/device/timeout

This will change the command timer, allowing the drive to do a long recovery and possibly enabling the bad sector to be read. I would do an e2fsck -f (assuming it's an ext fs). If it's a bad sector, and if file system metadata is on it, there's a possibility it can be fixed. Any writes to this bad sector will solve the problem, either by refreshing the existing sector's data or by remapping it if it's persistently failing writes too. You'll see all of this in dmesg.

If there are no errors in dmesg or fsck, then it's not fs metadata that's affected, it's data (binaries most likely). And that's slightly more difficult to fix. But if you just use
# exit
 that will continue with the startup process from the break. And the command timer change might allow the drive to recover this data. If not, at the very least, again if it's a bad sector, you'll get something in dmesg that's explicitly a read error and will have an LBA associated with it. Now you can find out what file's data is on that LBA using debugfs and reinstall that binary (hopefully) which causes the problem to be fixed also.
