Disk to disk imaging
by Mark Rogers 28 Sep '16

28 Sep '16

I have a 2TB drive I want to copy to another 2TB drive. They're attached as USB devices to my Ubuntu desktop. I don't want to shut down and use a boot CD (eg Clonezilla) because I want to keep using my PC in the meantime. Assuming I want to copy from /dev/sdX to /dev/sdY, I know I can use dd if=/dev/sdX of=dev/sdY .. but it'll be slow because it'll copy loads of empty space. I know I can use partclone, which "understands" various filesystems and can skip empty space, but that won't clone the partitioning itself, nor I assume will it copy any boot sector stuff? What's the bit I'm missing, and/or is there a better way?

Recovering a NAS
by Chris Walker 27 Sep '16

27 Sep '16

In 2009 I bought an Edimax NAS from Scan.co.uk and it's worked fine since, albeit with a change of hard drives. However over the weekend it wouldn't power up cleanly. Neither of the hard drive lights would come on and it wouldn't come ready. I also couldn't communicate with it in any way. I got in touch with Edimax and they suggested doing a reset on it. That at least allowed me to communicate with it and it came ready, but it said that the discs weren't installed correctly although it did show the partitions. I removed both drives (WD 1TB Red drives in RAID1) and using mdadm, I can see the contents of disc 1 and it all looks ok. If I buy another NAS box, is there any way I can simply put these drives in it and expect it to work, or should I expect the new box to have a different arrangement somehow of formatting? What I'm seeking to avoid is loads of copying and moving of files. Are there any recommendations from people here as to a small (I don't want huge amounts of storage and I power off the box when not used) NAS? -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

It is my understanding that much of a RAID drives configuration is actually on the drive itself with only some of it in the controller. Personally I would look on eBay and try to locate an identical unit which I would expect to 'just work'. However, if the worst comes to the worst and you are forced to copy huge tranches of files and are looking for a way to feel sure that the source and destination might actually match, plus you can put up with using Windows for a while ( assuming your disk formats are compatible ), I would thoroughly recommend trying a fabulous tool that must have been designed with us in mind. It is called 'Beyond Compare' by Scooter Software and I have been using it every day for over a decade. You can easily see what is on the source and destination disks side by side and copy all or part of you disk, at once or in recoverable stages and even compare multiple files and folders byte by byte to ensure all is well. See here :- http://www.scootersoftware.com/ Good luck, Noel ( Xorsyst ) _______________________________________________ main(a)lists.alug.org.uk http://www.alug.org.uk/ https://lists.alug.org.uk/mailman/listinfo/main Unsubscribe?

Transferring servers
by steve-ALUG＠hst.me.uk 20 Sep '16

20 Sep '16

Hi, My in-home server is at the end of it's tether, and I need to move to new hardware (motherboard, psu, case, fans etc) before the old one finally fails. This is a very stupid question. Under windows, in days of old (win 95, 98, xp for instance), I've had some success in the past, with just transferring hard disks into the new machine, and then installing relevant drivers. Would this work under linux? (I'm running xubuntu) If not, what's the best way to go? Installing the same version of xubuntu on the new machine with the same packages as the old one, then copying the data and config files, or copying everything from the old machine and then booting from a live cd and installing from there over the top of the transferred data, then tweaking or restoring the customised config files, or something else? I'm currently raided (Raid 1, 2 disks mirrored). Presumably I should do this again? I have a / and a home partition. Again, should I stick with this? Should I be using LVM (Logical Volume Management)? If so, how can I do it with RAID? Any/all advice gratefully received! Steve

Linux magazines
by Mark Rogers 20 Sep '16

20 Sep '16

I have various Linux magazines going back over several years that are taking up space. I'm tempted to keep them as an interesting archive of how things have progressed, but I'm also thinking of letting some/all go to recover some room on the bookshelf. Is there any interest here if I decide to let them go? If there's interest I can get some kind of list together, but over the years I've tended to subscribe to most Linux magazines (although not necessarily kept them all). It's unlikely I've still got many cover CD/DVDs. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Intltool install fails
by Chris Walker 11 Sep '16

I'm trying to install intltool in order that i can run Asunder - a CD ripping tool - but it's failing. There are lots of errors all along the same lines (all python related). Here's the first :- file /usr/share/glib-2.0/codegen/__init__.pyo from install of lib64glib2.0-devel-2.48.2-1.mga6.x86_64 conflicts with file from package libglib2.0-devel-2.48.2-1.mga6.i586 If both the i586 and x86_64 versions are the same, where is there a conflict and is there any way for me to resolve it? -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

Re: [ALUG] System battery low
by Bev Nicolson 02 Sep '16

Are these instructions ok? http://www.wikihow.com/Replace-the-Battery-in-Your-PC That's the kind of info I'd need. Step by step with pics if possible! Bev. On 01/09/16 11:03, Noel Galer wrote: > This seems to be simply a matter of the CMOS battery on the motherboard that maintains the NVRAM / BIOS settings running low. The matter of surge suppressors seems to be a red herring as the date of that thread is 2003. However, something seemed to be causing corruption of the CMOS, since a simple removal and replacement would not otherwise have cleared it permanently if the battery was actually low. Although probably not caused by a surge suppressor in your case, the CMOS could still be corrupted and removal / replacement / noting settings and reloading them might still work. However, the battery is probably near the end of it's life anyway and they are about £1 to buy. As an engineer I would have no issue changing the battery but can understand that others may be reluctant to do so. There therefore seems to be two choices for you, take it to a shop and pay for the battery to be replaced specifying clearly that they record the settings, clear the CMOS and restore settings again afterwards. Or do it yourself. If you decide to do this, I recommend using a loop of 'Sellotape' firmly stuck to the flat top of the battery before removal, this is for you to hold whilst releasing the clip that secures the battery. This will help prevent the battery slipping out of your hand and landing across exposed conductors / components, which if there is any life in the battery, could otherwise damage the motherboard. > > Best regards, > > Noel > > Noel Galer > > -----Original Message----- > From: main [mailto:main-bounces@lists.alug.org.uk] On Behalf Of Bev Nicolson > Sent: 01 September 2016 09:00 > To: ALUG > Subject: Re: [ALUG] System battery low > > On 01/09/16 08:38, Bev Nicolson wrote: >> That's the alert I just got on my Dell.

System battery low

That's the alert I just got on my Dell. I have googled but to be honest, I'm not confident about fixing this. The advice 'dhg' got here from Dell seems the one to go for but how do I do that? http://en.community.dell.com/support-forums/desktop/f/3514/t/1915445 Bev.
