[opensuse] migrating 12.3 etc. to SSD
Hi All, Is there anything special I should know about migrating my daily 'workhorse' openSUSE 12.3 installation over to an SSD, such as any filesystem(s) to use or avoid? Procedural tips & tricks or common 'gotchas'? I'm otherwise extremely good at moving installations around (drive to drive, partition to partition) but this is my first SSD. The situation is further somewhat complicated by the need to combine three separately installed OS's (on two drives) onto this one SSD, including one previously dormant but recently resurrected Windows Vista Home Premium (now a work requirement.) In case it matters, the SSD is a Samsung MZ-7PD512BW. Any and all links, comments & feedback will be welcome. TIA & regards, Carl -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

If that's the case, then no, no gotchas whatsoever, the SSD drive is seen by userspace as a regular hard-drive. -- Cristian "I don't know the key to success, but the key to failure is trying to please everybody." -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

But people often do some customizations, to minimize frequent write operations, mainly. I've not been paying much attention, but I think there are some options available on fstab for such devices. "man mount" mentions the ssd word, for instance. Some people move some directories out of the ssd: temp directories, logs... - -- Cheers / Saludos, Carlos E. R.

Yes, some filesystems have special support for ssd devices, at least BTRFS detects that automatically and no action from the user is needed.

Yes, I move them to RAM.. but not because of the SSD lifetime concern, but because I usually only want temp files and logs from the current boot. If I need something else I just activate the journal persistent storage. -- Cristian "I don't know the key to success, but the key to failure is trying to please everybody." -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Hello all

Take that info with a proverbial grain of salt. A lot of it applies to the previous generation of SSDs - such as explicitly overprovisioning.... using noatime (better to use relatime so you don't break apps that may require atime). Not saying things are incorrect on that site... just a good chunk of it is no longer necessary. A LOT of the hysteria over reducing writes stems back to the early SSDs that ran out of write cycles before you could sneeze. That is not really so much of an issue in current gen SSDs.

I want to add that ssd price is dropping every day, so that I'm sure one will buy a new one before the old collapse. a ssd is of no use with an old slow computer, but extremely impressive with a modern fats one, an my 128Gb ssd, installed like any other disk, wil probably be replaced by a bigger one pretty soon :-) jdd -- http://www.dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Thanks Cristian, Carlos, Ian, James & jdd - I really do appreciate the links and input. I'll report back any interesting observations or experiences next week after the upgrade. regards, Carl -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Mmmm don't know how much "no use". I've found that dropping an SSD into an older computer (eg older laptops) really breathes new life into them. You get a VERY noticeable performance boost moving from some old 5400RM mechanical drive to SSD... even if it's on the SATA2 bus instead of SATA3 (or PCIe) C. -- openSUSE 13.1 x86_64, KDE 4.13 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I have a not so old netbooc (acer approx 4 years old - 2Gb ram) and the ssd did not change anything to the computer speed. The atom was obviously the limit the ssd was then installed in my i5 tower and there it shines jdd -- http://www.dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

It really depends on what has to be read from disk. Booting typically involves reading a lot of files, so that is usually improved more. Another limit can be the board sata/pata chipset. - -- Cheers / Saludos, Carlos E. R.

My best half and I have two different models of the Asus EeePC. Except for the screen size and the hard drives they are pretty much the same. They both use the same Atom processor. Mine, with the SSD, always booted faster than hers with the mechanical drive. She replaced her mechanical drive with an SSD and saw a big difference. I also replaced the mechanical drive in my five year old Gateway dual core laptop. OMG! On bootup the POST takes longer than the actual operating system boot. Start a program and it's running. No watching the little bouncing icon for a minute and a half.

There I read: "Most modern computers with 2GB+ of RAM will rarely use swap space unless they need it to store data on the drive (such as the hibernate feature). The following is a tweak that will reduce the amount of writes to the swap area to help prevent the SSD from wearing out. " I explicitly set swap onto the SSD on my 12.1 system. Without any tweaks. With 16GB RAM it's max use of swap is around 100MB in a session. Also /var with leafnode files is on SSD. Does this matter? Is there a linux tool to check SSD wear out?

Not true. This desktop machine has 8 GiB, and it uses swap; after some days, perhaps 2 GiB, sometimes more. It really depends on what software you use and how you use it. I typically have many desktops and several applications open on each, and some of them are memory hungry, like Firefox with hundreds of tabs, Thunerbird with many large mail accounts (dozens of gigabytes of mail), libreoffice with several spreadsheets opened... And before someone tells me to buy more RAM, my board is maxed.
Is there a linux tool to check SSD wear out?
smartctl, depending on what the disk firmware tells you. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
