A tool for Ext? partitions.
by JD 15 Aug '14

15 Aug '14

Need a tool that can scan an entire drive (which has no partition table - as it got accidentally clobbered by dd'ing 512 bytes into it), and determine start and end of ext(2/3/4) partitions. I need this so that I can restore each ext? partition to a separate HD. So far I have found a windows based tool from EaseUS.com , but is not open source and is not free. Thanx, JD

--mke2fs pre-computes the ratio of number of inodes to total number of available block in the chosen partition are you implying/saying that there can only be a single inode count for a given patition size?? in my case, I'm going to have a large number of small files (2-5K) and I might have millions in my test.

stock f20 bootloader not signed
by patrick korsnick 14 Aug '14

14 Aug '14

Hi all, I just did a fresh f20 install in UEFI mode (no CSM) with secure boot enabled and while it booted the USB stick fine after the initial reboot I get an error about the bootloader not being signed and have to disable secure boot in order to boot the machine. I did a search on Bugzilla for the error message and didn't find anything. Has anyone encountered this error before? The machine is a HP Zbook 17 with the latest firmware (BIOS) update installed. Cheers

centos/fedora install without gui!
by bruce 14 Aug '14

14 Aug '14

Hi guys/list. Looking into installing centos/fedora and I'd like to increase the inodes on the partitions. So I'm trying to find a step by step process to accomplish this. As far as I can tell, the GUI/Anaconda doesn't have any place for me to insert the increased inode count. Comments would be appreciated. ps. I know I can take a partition offline, reformat it, and increase the nodes, but I don't see how one can do this with the primary/root portion of the drive on the same system.. thanks

ok... but given that I've asked for how to be able to install centos/fedora so I can increase the inode count!!!!! still trying to figure this part out! ie, where/how does one do the cmdline/level install and where would the attribute for increasing the inode count occur.. thanks On Thu, Aug 14, 2014 at 3:48 PM, jd1008 <jd1008(a)gmail.com> wrote: > > On 08/14/2014 12:29 PM, bruce wrote: >> >> Hi guys/list. >> >> Looking into installing centos/fedora and I'd like to increase the >> inodes on the partitions.

I'm running Fedora-20/KDE. I have had the same - quite nice - wallpaper for a month or so.

Hello Patrick, Actually, I have a dual laptop which has Windows 8 and Kali, and a Macbook with OS X and Fedora, I can confirm that Kali didn't work with Secure Boot enabled! I wasn't aware that fedora actually supports Secure Boot until I checked fedora docs about UEFI[1]. However, it is still not as simple as paying Microsoft to include their keys and also I do not think that the system is flawless, as I still hear many fedora users with their complaints on Secure Boot. You might be interested in checking this out, if you haven't already : [1] http://docs.fedoraproject.org/en-US/Fedora/18/html-single/UEFI_Secure_Boot_… Cheers, Madhurjya Roy FAS : madhurjyaroy IRC Nick (irc.freenode.net) : madhurjyaroy -----Original Message----- From: "patrick korsnick" <korsnick(a)gmail.com> Sent: ‎8/‎12/‎2014 10:51 PM To: "Community support for Fedora users" <users(a)lists.fedoraproject.org> Subject: Re: stock f20 bootloader not signed Hi Madhurjya, As I understand it Fedora paid Microsoft to register their key so Secure Boot does indeed work with Fedora.

Command line for creating partitions
by Robert Moskowitz 12 Aug '14

12 Aug '14

I am working now more on handcrafting my SD cards for arm testing. Gparted did not do a good job, allowing me to make parititions not on 'cylinder boundaries'. And the labels it created were not recognized when I mounted the drive. I had to use the disk utility to fix the labels. Anyway, to script it and to put this up on some wikis, I really need to do this by command line. So I have looked at both fdisk and parted. Neither are for 'simple' command lines. Fdisk takes me back to my DOS days (wonder where MS got it from?). So first I want a command that will delete all partitions on /dev/sdb then create a partition as ext3, then one as linux-swap, and finally ext4. Of course, I understand how many MB I want each, but I am suppose to (or so from the warnings that 'fdisk -l' provided) maintain boundaries. thanks for any pointers to the best tool(s) for this. So far my search foo has only gone to old fdisk pages.
