Fedora :: Re-establishing Soft RAID5 From Previous Install?

Jan 25, 2011

I had FC 14 installed on an SSD, and 4 500Gig drives in a software RAID-5 configuration. However, just recently, my FC14 failed horribly. Fortunately my admin had recently backed up the /etc directory. When FC14 failed, he reinstalled FC14 on the SSD. Is there any way for me to re-establish the RAID-5 drives, since they were not affected?

Nov 15, 2009

I have the Ubuntu 9.10 installed and another partition where I want to have Fedora.
But I would like to install it without messing up with the Grub 2 bootloader that I already have there.

Fedora Networking :: Establishing Ssh And Vnc For Remote Control Via Android Phone?

Jul 31, 2011

i want to remote control my laptop with my phone via terminal

im trying to use this guide to connect my android phone to my fedora laptop via ssh and vnc, but the connectbot ssh connection is timed out


however, this guide assumes a running ssh and vnc server, which isn't trivial to me, i think i have established these, but i don't know how to test it

also i am not shure if my router and firewall configuration is correct, i disabled wan blocking but didn't enable remote config management on my rooter, is that correct?

Fedora Networking :: Establishing A Vpn Connection Using Vpnc / Error Failed To Bind To Address Already In Use?

Nov 24, 2010

I am having difficulties in establishing a vpn connection using vpnc (or NetworkManaager-vpnc).

As long as the openswan IPsec daemon is running, vpnc-helper quits with the error message


Failed to bind to Address already in use
[user@computer ...]# vpnc-helper --local--port 0

If I use NetworkManager-vpnc, then establishing the connection simply fails.
Using the --local-port 0 option does not change anything.

If I stop the ipsec service (service ipsec stop) then establishing the connectiong works, both with NetworkManager-vpnc and the console tool, but apparently the network traffic is not routed via the VPN - in my case this means that I cannot access hosts within the vpn and stuff.

Funny thing is - on my notebook from where I connect via WLAN, everything works fine. With Fedora 13 everything works fine, too.

Does anybody have an idea how to enforce that the vpn connection is actually used?

OpenSUSE Install :: Soft Lockup: CPU# Stuck - 11.4

Mar 23, 2011

11.4 Boot Freeze That is there is a BUG: soft lockup - CPU#0 stuck message and the boot hangs.The modprobe/migration codes are not identical with the linked thread. I'm stuck with CPU#0 at [modprobe:138] and #1 stuck at [migration1:8]. Generally after 61 or 63s.

This is a zypper dup from latest 11.3.The machine boots with acpi=off, luckily. But I'd like to have it all working.The forum says I can't post attachments; hwinfo output seems a bit copious to quote inline. But I'd be happy to provide any additional info obviously.

Server :: Recreate A Raid5 MD0 Into A Raid5 MD3?

Jan 9, 2010

I have no drive failures but just need to recreate a raid5 set as the next free MD disk number. Originally I built a temp OS of debian on a single drive and had 4x2TB drives in a raid5 software array (MD0) this worked fine and allowed me to move all data to it, and remove our old fileserver. I have now pulled out the 4 x 2TB Raid 5 drives and created a new OS on two new 80GB drives, partioned as follows,

MD0 is now 250mb Raid1 as /boot
MD1 is 4GB Raid1 Swap
MD2 is 76GB Raid1 as /

If I turn off and push back in the 4x2TB drives I cannot see a MD3. I presume I would need to create a MD3 from these 4 drives but I dont want to mess things up as its live data. So im here asking for help, or a bit of hand holding to get it done right.

PS - Its a Debian Lenny 5.0.3 Raid1 fresh install replacing a Debian Lenny 5.0.3 on a single disk.

Fedora :: Gnome Soft On Small Monitor (netbook)

Oct 28, 2010

I am using F13 on my netbook for a week so far. Its worth mention, I am completely new new to Linux. Want to say many thanks to Fedora developers for such a great OS, it makes me really happy.
Now, on the subject, I have a very small monitor 1024x576, this is causing difficulties with GIMP, and more, I found that GIMP is too much 'overfeatured' :-( . Searching on this forum , I found posts about 'Kolour' for KDE desktop. Maybe you can recommend a similar simple image editor for Gnome desktop? Crop/resize and pencil tool where i can pick up color and draw pixels will suffice most of the time.

Also I am using Firefox a lot and thought whether it possible to get a small feature , I will try to describe it: when the window is maximized I want to hide the window's header and menu, which would give me extra 40-50 pixels height to the contents of the window.
Yeah, I know I can hide navigation bar, but how then I will type the page location?

Fedora Installation :: Soft Linked Yum Cache For Upgrade Doesn't Work?

Is there any more sofisticated way around than changing parition sizes and copying and stuff?

OpenSUSE Install :: 11.0 Raid5 LVM Logical Volume Not Mounting?

Apr 22, 2011

I have a raid 5 with 5 disks, I had a disk failure which made my raid go down, after some struggle I got the raid5 up again and the faulty disk was replaced and rebuilt itself. After the disk rebuilt itself I tried doing a pvscan but could not find my /dev/md0. I followed some steps on the net to recreate the pv using the same uuid then restored the vg(storage) using a backup file. This all went fine.I can now see the PV, VG(storage) and LV's but when I try to mount it, I get a error "wrong fs type" I know that the lv's are reiserfs filesystems, so I did a reiserfsck on /dev/storage/software, this gives me the following error:reiserfs_open: the reiserfs superblock cannot be foundNow next step would be to rebuild then superblock, but I'm afraid that I might have configured something wrong on my raid or LVM and by overwriting the superblock I might not be able to go back and fix it once I've figured out what I didn't configure correctly.

OpenSUSE Install :: RAID5 Array Fails To Automount After Reboot

Apr 26, 2009

I've got a RAID5 array that doesn't want to automount after rebooting. I'm pretty familiar with linux, RAID, and mdadm, and up until now, I've had the RAID5 array working just fine. However, whenever I reboot, the array drops off and won't remount until I manually assemble and then mount the thing. I find this odd because I had everything automounting just fine back in 10.3, and even in 11.0 (I think - not sure on that). Currently, things are working, but I'd really like to not not have to type

mdadm --assemble /dev/md0 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1
followed by
mount /dev/md0 /mnt/data every time I reboot. Even including this in some sort of start-up script seems kludgey... Surely there must be a more elegant way of automatically bringing up a RAID5 array after booting? I'm not sure what information you'll need, so I'm going to go ahead and include as much as I can anticipate...

So having already used the commands:

General :: Ubuntu Server Install Wipes Out RAID5 Settings?

Jun 8, 2010

I have a 2-quad core Intel Xeon system that I have set to RAID-5. I then attempted to install Ubuntu Server. When the message came up about enabling SATA RAID, I said NO because I have hardware RAID installed on the box. So I completed the install, and when I go to view the RAID configuration using the Intel Matrix Storage Manager during boot, it says:Volume0, Level: RAID5(Parity), Status: DegradedWhen I install enabling SATA RAID, I get a message asking me to "configure iSCSI volumes". When I click on that, I get another message: Loginto iSCSI targets. When I click on that I get another message: "Enter an IP address to scan for iSCSI targets". I have no idea what to put as thye iSCSI target portal address!

My /store/mysql was copied back over, changes to /etc/mysql/my.cnf and /etc/apparmor.d/usr.sbin.mysqld, but MySQL hangs when I go to start it and nothing is showing up in any of the logs. How do I get MySQL to recognize the datadir from the previous install?
