| 14:16 | <huslu:#uml> | hi jdike , i'm trying to resize (grow) a ext2 partition as shown in your book with debian resize2fs. but there does not seem to be /dev/ubda even tho df shows that / is mounted from there. |
| 14:16 | <jdike:#uml> | what ubd* are there? |
| 14:17 | <huslu:#uml> | none, only thing starting with u is /dev/urandom inside uml. |
| 14:17 | <jdike:#uml> | odd |
| 14:18 | <jdike:#uml> | this is otherwise a healthy-looking system? |
| 14:18 | <huslu:#uml> | yea, so far |
| 14:19 | <jdike:#uml> | you can just make it |
| 14:19 | <jdike:#uml> | but udev should have done the job on boot |
| 14:27 | <huslu:#uml> | wierd, somehow udev is not installed on that system |
| 14:27 | <huslu:#uml> | i guess better do it now and reboot |
| 14:30 | <huslu:#uml> | resize2fs: Kernel does not support online resizing, hmm what am i missing? |
| 14:31 | <jdike:#uml> | what UML version? |
| 14:32 | <huslu:#uml> | 2.6.24.6 |
| 14:32 | <jdike:#uml> | certainly new enough |
| 14:32 | <huslu:#uml> | did i leave something out? |
| 14:33 | <jdike:#uml> | dunno |
| 14:33 | <jdike:#uml> | are there ext* docs for this |
| 14:33 | <jdike:#uml> | ? |
| 14:33 | <jdike:#uml> | there shouldn't really be anything UML-specific about this |
| 14:47 | <huslu:#uml> | probably, i wonder if i something that's supposed to be in kernel is left out. |
| 14:56 | <jdike:#uml> | could be |
| 14:56 | <jdike:#uml> | see what options there are for ext* |
| 15:05 | <huslu:#uml> | most are set |
| 15:05 | <huslu:#uml> | CONFIG_EXT2_FS=y |
| 15:05 | <huslu:#uml> | CONFIG_EXT2_FS_XATTR=y |
| 15:05 | <huslu:#uml> | CONFIG_EXT2_FS_POSIX_ACL=y |
| 15:05 | <huslu:#uml> | # CONFIG_EXT2_FS_SECURITY is not set |
| 15:05 | <huslu:#uml> | CONFIG_EXT2_FS_XIP= |
| 15:07 | <huslu:#uml> | altho i have resize2fs 1.40.8, http://lxr.mstier.de/e2fsprogs/source/e2fsprogs_1.40.3/resize/online.c shows the line with my error |
| 15:17 | <jdike:#uml> | So, EXT2_IOC_GROUP_EXTEND failed |
| 15:18 | <huslu:#uml> | yea, which i have no idea what it is or where it comes from. |
| 15:19 | <jdike:#uml> | that ioctl doesn't appear in fs/ext2/* |
| 15:28 | <huslu:#uml> | hm, i have only /proc/fs/nfsd/ direcory, no ext2 |
| 15:34 | * | huslu:#uml scratches his head. |

| 16:25 | <huslu:#uml> | well, the issue is solved, i couldn't resize the fs 'online' from insde uml. i just halted to uml, run resize2fs on the file from the host and restarted the uml. |
| 16:26 | <jdike:#uml> | hmm |
| 16:26 | <huslu:#uml> | but i still wouldn't mind knowing what was the problem that didn;t let me do it from inside |
| 16:26 | <jdike:#uml> | same resize2fs in UML and on the host? |
| 16:27 | <huslu:#uml> | yea, both are the updated debian lenny installs |
| 16:29 | <huslu:#uml> | mke2fs that made the image file originally was 1.40.2, if that helps any |
| 16:43 | <jdike:#uml> | dunno |
| 16:44 | <jdike:#uml> | diff the two configs and see if grep EXT shows anything interesting |
| 16:46 | <huslu:#uml> | that might harder, my uml kernel has config.gz support in prov, but host debian kernels don't have it. or is there a way to get extract it? |
| 16:46 | <huslu:#uml> | prov=proc |
| 16:46 | <jdike:#uml> | linux --showdonfig |
| 16:46 | <jdike:#uml> | showconfig |
| 16:47 | <huslu:#uml> | hah, config file was right in /boot in debian. k, i'll check it out |
| 16:49 | <jdike:#uml> | Oh whoops |
| 16:49 | <jdike:#uml> | thought you were talking about UML |
| 16:49 | <huslu:#uml> | er, which part of talking you mean? |
| 16:51 | <huslu:#uml> | for my uml kernel CONFIG_EXT2_FS_SECURITY is not set but for my host kernel it is |
| 16:52 | <huslu:#uml> | and uml kernel does not has EXT3 support as i was not intending to use it.. |
| 16:53 | <jdike:#uml> | when I said --showconfig |

| 17:12 | -!- | Basic [~Basic@gatekeeper.real-time.com] has quit [Read error: Connection reset by peer] |
| 18:10 | <huslu:#uml> | either way, uml kernel has config.gz in proc, and the diff as far as the CONFIG_EXT2* options go is the CONFIG_EXT2_FS_SECURITY |
| 18:42 | * | huslu:#uml has one more question. |
| 18:42 | <huslu:#uml> | should there be done any special preparations for compiling uml kernel inside uml guest ? |
| 18:44 | <huslu:#uml> | when i do 'make ARCH=um' for 2.6.25.9 i get an error for kernel/sched.o |
| 18:45 | <huslu:#uml> | In file included from kernel/sched.c:1315: |
| 18:45 | <huslu:#uml> | kernel/sched_idletask.c: In function .check_preempt_curr_idle.: |
| 18:45 | <huslu:#uml> | kernel/sched_idletask.c:20: internal compiler error: in cgraph_estimate_size_after_inlining, at ipa-inline.c:188 |
| 19:07 | <jdike:#uml> | hmm |
| 19:07 | <jdike:#uml> | there should be no UML-specific stuff there at all |
| 19:07 | <jdike:#uml> | I do kernel builds (including UML builds) inside UML all the time |
| 19:08 | <jdike:#uml> | that looks more like a gcc bug than anything else |
| 19:08 | <jdike:#uml> | what gcc version? |
| 19:08 | <huslu:#uml> | that's good to hear. i was using gcc-4.3 (Debian 4.3.1-2) 4.3.1 |
| 19:09 | <jdike:#uml> | OK |
| 19:09 | <jdike:#uml> | I have one other report of UML provoking a gcc internal error |
| 19:10 | <jdike:#uml> | that was with 4.3 too |
| 19:10 | <jdike:#uml> | if you have a git tree, see commit 22eecde2f9034764a3fd095eecfa3adfb8ec9a98 |
| 19:10 | <huslu:#uml> | i don't. was that report for 25.9 too? |
| 19:13 | -!- | BasicOSX [~Basic@gatekeeper.real-time.com] has quit [Quit: BasicOSX] |
| 19:19 | <huslu:#uml> | 25.8 produces the same error in the same place (compiled in same uml instance) |
| 19:21 | <huslu:#uml> | but 25.9 compiled fine with gcc 4.1.2 20061115 (prerelease) (Debian 4.1.1-21) on a different physical box (not insde uml instance) |
