Either way I don't think a sweeping condemnation of the entire product is the right way to go. I read that entire thread back when it was highlighted on /. 1) The vbox driver is buggy. 2) The vbox driver is buggy in ways that cause crashes which are difficult to debug and correctly attribute, which appears to be discerned by statistical means. 3) The vbox driver upstream won't send their code to the kernel where it could be cleaned up and kept in step with the rest of the kernel, because it would restrict them from updating their API in future versions. 4) The vbox driver functions as a wildcard when kernel devs are trying to deal with bug reports in other areas of the code; just like heap and stack corruption in userland apps are a royal PITA to deal with, so are the same in kernelspace. The vbox driver is known to cause these problems, so they don't want to deal with it. Now, it looks like things may be in line to get better; the thread got the attention of the vbox maintainers, and they started working on ways to get flagged bug reports sent their way. That'll improve the feedback they get. The code will probably improve as a result. That said, drivers which cause random memory corruption are *not* ones I want loaded into my kernel. Discussions around things like the vbox kernel give me second thoughts about sweet dreams of mmapping persistent storage block devices contiguously in a large address space; I'd suddenly rather keep the window target small. I've got nothing against proprietary drivers if they're good. I've generally had good luck with both NVidia and ATI, for example. NVidia, especially, has been quick to respond to issues by their user communities Oh, I forgot something in the first paragraph. In my experience on this machine we can add Firefox, OpenOffice.org and LibreOffice to the same list of unstable software. Apples and oranges. FF, OO and LO don't crash the entire system when they go up. Protected memory FTW. Kernelspace stuff must be held to a higher standard; they run in ring 0.

According to the nvidia site it seems you want the

in portage right now. Most likely it's coming soon, and I would guess
the 290.06 version that I'm running here for a 465GTX card will work
fine for you. 290.1 was only released 2 days ago.

I have to reduce the file system, change the partition in cfdisk (?), resize the lv, then reduce the vg, then I can run pvmove? After all that, I can remove the drive sdb? Do I have the order correct too? If it does involve all this, I'm not sure I want to do this. The file system and cfdisk part makes me nervous. Maybe some of this isn't needed and I am reading some of the info incorrectly, I hope. No need for cfdisk. Just shrink the file system, and then the logical volume. You can keep the VG as it is, as you move stuff around inside the same VG. BTW, I also tend to make lots of partitions on a drive, all belonging to the same VG, so I can more easily change things later. Like freeing a partition in case some other OS needs space for itself or something like that. I tend to shrink the file system to a size somewhat smaller than the logical volume, just in case there is some additional header or something, or different utilities use different units (megabytes vs. mibibytes). Calling resize2fs afterwards enlarges the FS to the maximum size. I wrote a script to automate this, it also takes care of a LUKS volume on the LVM. And is easier to use than doing all those steps in a row. And I trust it more than me making a typo in one of those commands. But I don't think I would use such a thing written by some guy, and prefer to just do it myself. Wonko

I use good ole' rsync, together with a couple of scripts. It does the hard link-style incrementals and I can do a near-bare-metal restore. From that. rsync is still maintained afaik.

I read a thing somewhere that was talking about calculating blocks and such and I didn't want to go down that road. I have Kcalc on here but still. So, the commands is something like this: resize2fs /dev/mapper/data-data1 400G this should make the VG a absolute size of 400Gbs which leaves a little room left over. If I used a - in front, it would reduce by that amount. lvreduce -L 400G /dev/data/data1 I assume I can make this the same size as above? pvmove -v /dev/sdb1 pvremove /dev/sdb1 Showing info for clarity here: root@fireball / # df Filesystem 1K-blocks Used Available Use% Mounted on rootfs19534436 7249480 12284956 38% / /dev/root 19534436 7249480 12284956 38% / rc-svcdir 1024 120 904 12% /lib64/rc/init.d udev 10240 360 9880 4% /dev shm8232972 0 8232972 0% /dev/shm /dev/sda1 186663 28128148898 16% /boot /dev/sda8 9614116 4366728 4759016 48% /var /dev/sda6 11535344 5332948 5616428 49% /usr/portage /dev/sda7 48828008 11273208 37554800 24% /home /dev/mapper/data-data1 960906608 276328616 635775728 31% /data tmpfs 8232972 0 8232972 0% /var/tmp/portage /dev/sda9 59434744 31373872 25041732 56% /mnt/temp root@fireball / # lvdisplay --- Logical volume --- LV Name/dev/data/data1 VG Namedata LV UUIDZvsgH6-PI0M-NqVd-op9P-Crsy-IEnz-iKoTfp LV Write Accessread/write LV Status available # open 1 LV Size931.00 GiB Current LE 238336 Segments 2 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 254:0 root@fireball / # vgdisplay --- Volume group --- VG Name data System ID Formatlvm2 Metadata Areas2 Metadata Sequence No 4 VG Access read/write VG Status resizable MAX LV0 Cur LV1 Open LV 1 Max PV0 Cur PV2 Act PV2 VG Size 931.46 GiB PE Size 4.00 MiB Total PE 238454 Alloc PE / Size 238336 / 931.00 GiB Free PE / Size 118 / 472.00 MiB VG UUID eNF7B0-3BDb-qe1W-5FTH-4Uah-wRe1-xD7Xa8 root@fireball / # pvdisplay --- Physical volume --- PV Name /dev/sdb1 VG Name data PV Size 232.83 GiB / not usable 2.55 MiB Allocatable yes (but full) PE Size 4.00 MiB Total PE 59604 Free PE 0 Allocated PE 59604 PV UUID Nxvrjn-BuaK-RGsF-F32S-0EaI-W4xe-H6Lnjl --- Physical volume --- PV Name /dev/sdc1 VG Name data PV Size 698.64 GiB / not usable 4.84 MiB Allocatable yes PE Size 4.00 MiB Total PE 178850 Free PE 118 Allocated PE 178732 PV UUID NF6I4G-L1L5-0VDE-HyUc-ESH3-CfV3-eUo676 root@fireball / # Now for my piece of mind.

[gentoo-user] glibc-2.14.1 upgrade
Hi, After emerging glibc-2.14.1 today, pam stopped working, which prevented KDE from working and some other things. I got this kind of message: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /lib64/libcrypt.so.1) There were no @preserved-rebuild and revdep-rebuild found nothing. I rebuilt pam and things seem to be working again. Are there any other packages I should rebuild before encountering a problem? Or some way to detect which need to be rebuilt? Should I re-emerge world against my new glibc? :) Thanks, Paul

I set up rsnapshot a few months ago, and so far it seems to be working fine. I found the documentation about how to configure the intervals and schedule the jobs to be a bit confusing, but once the light bulb went on, it's pretty easy. -- Grant
