Very helpful - not. I don't know if it is safe having userspace lvm2 |
| 9 |
tools compiled with a newer/different version of gcc than the kernel |
| 10 |
(which has lvm2 compiled in). Maybe someone here knows - and maybe |
| 11 |
that's why I asked. |

I'm a user, not a programmer. I looked in an ebuild once - it was |
| 19 |
interesting, but didn't tell me a whole lot. I also have been bitten |
| 20 |
more than once by major changes to a package that came in a minor |
| 21 |
version bump that wasn't documented in the ebuild or anywhere else, so |
| 22 |
I've learned to be careful, especially where critical system updates are |
| 23 |
concerned (like lvm2, gcc and the kernel). |
| 24 |
|
| 25 |
My question was directed toward people who use lvm2 and (hopefully) know |
| 26 |
the answer... googling didn't reveal an answer (or at least I didn't |
| 27 |
find the proper incantation)... |
| 28 |
|
| 29 |
So, again, does anyone know if the new version of lvm2 (with integrated |
| 30 |
device-mapper) will work ok on the 2.6.23 kernel, or is there a minimum |
| 31 |
version required? |

Ever heard of a PHB? |
| 40 |
|
| 41 |
I don't upgrade the kernel very often, nor have to fix blockers |
| 42 |
manually, so I'd rather ask a few questions (admitting I don't know |
| 43 |
everything - or even much of anything - in the process - try it Alan, |
| 44 |
it's actually quite liberating), and not dig myself into a hole I may |
| 45 |
not be able to dig myself out of easily. |

What does your question have to do with mine? Look, I appreciate any |
| 54 |
help I can get here, but try reading the question you're responding to |
| 55 |
if you're going to take the time to respond (you missed the stuff in |
| 56 |
parenthesis)... |

Exactly - thank you Sebastian... |

Interesting - I don't use modules on a server, I only build with with |
| 72 |
what I need compiled in... so no modules/module support at all, but |
| 73 |
that's good to know if I ever decide to use Gentoo on the desktop - thanks. |

Yes, that I was planning on doing when I got approval to upgrade the |
| 79 |
kernel, but I figured I'd include the kernel version out of concern for |
| 80 |
the newer version of lvm2... |
| 81 |
|
| 82 |
I was already leaning toward the kernel upgrade first as being the |
| 83 |
safest solution (then fix lvm2, then switch compilers, update everything |
| 84 |
else, then rebuild world), but I have to justify it to the boss, which |
| 85 |
is why I asked in the first place... |
