Ok, Im likely to buy SSD 128gb drive and install Fedora 14 on it...but I have a question. If I go with ext4 will I get TRIM to work out of the box? Whats the status of kernel support on trim?
View 8 RepliesIn windows the only controllers that really work with TRIM is the onboard Intel ones, Jmicron, Marvell, Nvidia and AMD's don't pass the command to the drives if you use their own drivers. (And from what Ive read, the Micron sata6 controllers don't work with TRIM even using the default Microsoft drivers). In Linux do more then just Intel drives work with TRIM? I have a Nvidia 790i Ultra motherboard, the SATA controller is an Nvidia one which has 2 settings, ATA and Raid (if the drives aren't added to an array it runs them in AHCI) and has an additional Jmicron sata port.
If I enabled TRIM in the OS, would it work on either of those controllers? Also if anyone knows this, in Windows if you set an Intel controller to raid, you wont get TRIM on SSD's that are on the controller (but not in an array) with the default Microsoft driver like you would if it was set to AHCI, you only get it with the Intel RST drivers. Would a SSD on an Intel controller set to raid but not in an array get the TRIM command passed to it in Ubuntu?
I am wondering if Ubuntu support ATA TRIM for SSD out of the box?
View 1 Replies View RelatedI was running it portable on a 4gb usb drive via virtual box which worked great unless I used a computer that had virtualbox on it. The portable version would remove files that the original version needed. I decided to try Qemu. The problem is that the portable version only allows 1gb of space to install regardless the size of a usb drive. so the question is: Is there was a way to trim ubuntu 9.10 down to less than 1gb of disk space? If not is there another portable emulator that could be used instead? the only uses for this are for the use of evolution and opera in a linux environment.

The RAID management will be handled by a hardware Adaptec controller. I've learnt that the TRIM function for SSD drives is supported starting from kernel 2.6.28.
View 1 Replies View RelatedI have an OCZ Vertex SSD...the 30GB variety. recently I upgraded my kernel to 2.6.33. I have read that that is all that is needed in order for trim to just start working. Is there a way that I can verify that TRIM is working?I'm debating getting the Vertex2 100GB model because I love my SSD now, but would love to have a little more storage space. I just don't want to buy it without TRIM working.

View 6 Replies View RelatedI followed this tutorial [URL] to enable my TRIM support and now my fstab looks like this:
Quote:
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).

As I get more comfortable with Linux I find that I am doing more waiting for the computer to catch up.
Would it be better to trim down KDE or change to a lighter GUI? If I change to a lighter GUI will I have to reinstall things I have installed under KDE?
Does CentOS 5 support the ATA TRIM command for use with SSDs? Is the support automatic by default, or would I need to do something specific in order to enable the TRIM feature be used?
View 1 Replies View RelatedI am trying to set up an atom D525 low power PC 64-bit with a 40 GB solid state disk drive. Is it possible to specify ext4 during the install for proper SSD suupport? I read somewhere that after install I can place a -discard line in fstab to enable trim.
Edit: should I have asked this in the x86_64 forum, as I was planning on installing 64 bit?
I just bought a Samsung 850 Pro 250GB SSD drive and have since then found out that Linux has/had a faulty implementation of queued trim (which is a synonym for NCQ I think). I'm using kernel 4.1.0 (the default selected by the Debian 8.1 installer) and I've read that Samsung drives are blacklisted for queued trim by the recent kernels. However, the output of dmesg contains the following lines, with and without TRIM enabled for the drive (i.e. with or without the "discard" option in fstab for the drive):
Code: Select all[ 1.012287] ata6.00: 1953525168 sectors, multi 16: LBA48 NCQ (depth 31/32), AA
[ 1.013438] ata5.00: failed to get NCQ Send/Recv Log Emask 0x1
[ 1.013440] ata5.00: 488397168 sectors, multi 1: LBA48 NCQ (depth 31/32), AA
[ 1.015037] ata5.00: failed to get NCQ Send/Recv Log Emask 0x1
Since the depth is not 1 but rather 31, it looks like NCQ is enabled. I've disabled TRIM on the drive for now, and whether it's safe to enable TRIM or not.
Does Suse have any software based TRIM support available or that is in the works?I know there is to a degree new firmware becoming available that supports TRIM (although some are pretty rudimentary) but windows 7 does a fairly good job software side and upgrading the firmware occasionally involves the unbridled joy that is wiping the drive and starting again.
View 1 Replies View RelatedThere are not SSDs with TRIM support available in my region that fit into my laptop (1.8", IDE, ZIF). I'm running Ubuntu 10.10.
Most articles (or questions on superuser) I've come across concering TRIM (or the lack thereof) date back to 2009, when not many SSDs with TRIM support were available and OS support was still very fresh.
I'm interested in the current situation, but I couldn't find too much information about it.
What are currently the "best practices" for using an SSD without TRIM under Linux?
I've read about the wiper script included with hdparm. Do I understand correctly that I could use this to free unused blocks, e.g. by running it once a month?
Some sources state that HFS+ (the default-filesystem of Mac OS X) doesn't suffer as badly from lack of TRIM as other filesystems. How about linux filesystems? Are there filesystems that are better suited for SSDs without TRIM than others?
My partition /dev/sda3 on an SSD drive doesn't contain any filesystem, but it contains garbage. How do I do a TRIM/DISCARD operation on the whole partition?
View 2 Replies View RelatedThe situation with TRIM in Ubuntu has me utterly confused. I don't know whether I need to manually run it or not. Sources I've found are disparate and unclear. I have Ubuntu 10.04 with latest updates (including kernel 2.6.32-26). I have an Intel X-25M drive with latest firmware, and it is formatted as ext4. So, does TRIM support run automatically? If not, how do I check if I need to run it, and then how do I run it if necessary?

View 14 Replies View RelatedI'm moving over to Linux when the new SSD arrives. SSD gives increased performance, so I thought that I could encrypt everything.
But then I came to think about TRIM, and garbage collection on the drive. Will a LUKS encrypted drive affect the garbage collection system? (TRIM).
I have a bunch of files (around 900) that have some special characters. Some of the files contains example, and quoting "[useless] filename (something)"so what I want is just to strip the brackets and parenthesis, some are folders, others are text files

Code:
ffmpeg -ss 00:20:48.500 -t 00:01:00 -i INPUT.mp4 -acodec copy -vcodec copy OUTPUT.mp4
But FFmpeg is not accurate and it started the video from a nearby point instead (from 00:24:46~). I tried to add 2 seconds to my starting point and it took another frame (not what I wanted).
The video source is H264 video with AAC audio.
I wrote this script which works but it should run automatically about once per week. I hunted and experimented with KDE Task Scheduler (no dice and no help anywhere) and cron (confusing instructions and cannot edit crontab -e with vim, and cannot enter cron folders/files).

I'm looking for a way to launch "TRIM" commands to a SSD drive myself, from a c++ code I'm going to write, for flash erasing an SSD drive (and not to wait for others things that "should do it automatically in some circumstances if this or this, this and this have been enabled and [..]" but will never tell me if it worked or not
I know there is thousands of complicated ways to test and check if it worked, and also software that needs money to do so, that's why I just want to call myself the TRIM functions and read the return value (like true or false) in order to know if it worked !
Where I can find the c++ call that could permit me to do so ? I heard about the GLibC that gives a way to access every user space function related to Linux Kernel (poll, select and others) as standard c++ functions, I suppose that, if there is a way, it will be on the GLibC but how to find it ?
With the new Intel G2 SSDs coming out, I'm thinking about upgrading my hard drive. However, there seems to be an extra level of software support needed for SSD drives. From what I have read there can be performance degradation over time and other issues. Does anyone know how well SSD drives are supported in Linux and also if there is support for the TRIM command or if it is planned?

What used to work flawlessly in F14 now does not work in F15. I have done a fresh installation of F15 and all seemed to go well other than a few minor tweaks. In F14 I had an /etc/fstab file that worked well but in F15 does not work. I have 3 external USB drives, mybook, black & StoreIt. With F14 my fstab worked very well and booted regardless of weather or not any particular drive was connected at any given time. Typically I have the mybook and black connected at home and the StoreIt connected at work, but regardless it would boot and work without any problems.

Is it possible to import an xorg.conf file from Debian to Fedora and have it work? The reason for this is that I have an older monitor that only offers 800x600 as the maximum resolution.
View 2 Replies View RelatedI have a Samsung N130 with a Realtek 8192 wifi card (possibly 8192e, I'm not sure) and I am trying to run Fedora 12 on it. I used to run Ubuntu until trying their latest beta and realizing it's not very good, so I looked for something else. Ubuntu was at least easy to get the wifi working with just a few quick commands that were written out, word for word, in order, on the Ubuntu forums. I tried openSUSE on here and it didn't have wifi working out of the box either but people on their forums refused to give me actual instructions and just kept bumping me from thread to thread with people giving vague advice or else just telling me I was looking in the wrong place. I'm hoping that someone can give me clear and detailed instructions on how to get this wifi card working. Keep in mind that I am coming from Ubuntu and so I'm not super comfortable in CLI, if I need to do some CL stuff I will need clear and detailed instructions on how to do that.

View 2 Replies View RelatedFedora (2.6.34.6-47.fc13.x86_64) I installed that update, during the installation process it said that it had to remove three packages, one of them was kmod nvidia for the old kernel (Fedora (2.6.33.8-149.fc13.x86_64))After the update finished installing the new kernel, I restarted the system and Nvidia did not load. (I assume because Update manager removed the old nvidia? But I also assumed that a new version would be installed automatically?)I received the following Boot messages:
Code:
Entering non-interactive startup
Starting monitoring for VG vg_user1: 3 logical volume(s) in volume group "vg_user1" monitored
[code]....
I'm confused, if Update Manager removed kmod nvidia, then why does yum say it is installed? And why doesn't the new kernel update work with that version? Or should I install a driver version for that particular kernel? I've read while searching that I need to install a kmod-nvidia for that particual kernel version and that I should login to my previous kernel until that happens, is that the problem I'm having?
Why don't rpmfusion and fedoraproject release the kmod-nvidia and kernel updates at the same time to avoid problems such as this? Does anyone know how long does it usually take for rpmfusion to release the new kmod-nvidia driver for the latest kernel?
