[gentoo-user] no javac on gentoo amd64?
hi, my system is gentoo amd 64. java-config -L show i have two VMs on my system: The following VMs are available for generation-2: 1) IcedTea6-bin 1.7.1 [icedtea6-bin] *) Sun JRE 1.6.0.18 [sun-jre-bin-1.6] but when i ran javac, it says: * javac is not available for sun-jre-bin-1.6 on x86_64 * IMPORTANT: some Java tools are not available on some VMs on some architectures we do not have javac on amd64 system? how to fix this? i did not find much use information on http://www.gentoo.org/doc/en/java.xml -- Best Regards, David Shen http://twitter.com/davidshen84/

The JRE (Java Runtime Environment) only has the Runtime tools.
You need to install the JDK.
It works on my system:

[gentoo-user] Disk or filesystem issue?
For the last few weeks i have been getting the single user prompt on shutdown, and reiserfs3 is performing a check(fix?) during boot. Seems to happen about 4 times out of 5. smartctl report looks ok. I have been using 2.6.31-gentoo-r6 for ages without issue. Any ideas?

Since the last big partition is big due to physical reasons (not for logical one): What will happen, if -- for example -- one portion will be not unmounted cleanly and while booting/checking fails to recover? Are all others damaged/lost? No, because the failure you describe is at the filesystem level. Even the volume containing that filesystem will retain integrity, only the filesystem itself will be corrupted. As you have left free space on the volume group, you can just create a new volume, format it and copy over everything you can recover from the broken filesystem before deleting it. Hi Neil, yes, sounds good, very good. Last question: How heavy is the performance impact of such a setup ? seriously lvm sounds nice. But it isn't. It easily breaks. Can you back that up with some facts? I use LVM on many machines and have never had it breaks. I'm also quite ruthless on some machines with how I use it - manipulating volumes with apparently gay abandon. I attribute this lack of failure to me understanding how LVm works and using it as designed, without trying to be cute and/or clever. You want a save setup? Go raid5 or raid6. As a bonus - you can get more space if you need it by just adding another disk. And you are not depending on some complex stuff to get it working. The various raid levels do not address the problem that LVM solves - how to rapidly create and manipulate sub-volumes. If your /var/log fills up, how would you add an extra 10G to it to gain breathing space without using something LVM-like (evms is for example LVM-like. So are the native HP-UX tools)? -- alan dot mckinnon at gmail dot com

Re: [gentoo-user] Re: language [solved]
Try $LC_ALL=fr_FR.UTF-8 gedit I did it, but it opens gedit in english. The idea came to search where the config file of gedit is on my desktop computer. I made a locate gedit and I found within other files /usr/share/locale/fr/LC_MESSAGES/gedit.mo I saw that gedit.mo is a binary file. With an usb key I put it in /usr/share/locale/fr/LC_MESSAGES of my laptop where it wasn't. And it worked :-) I made a second try with xfdesktop.mo, and it succeeded also. Now I have to do the same thing for the other packages. I'm surprised that the video projector could change the language in many files. Thanks for your help Roger

[gentoo-user] How does grub assemble a RAID1 for / ??
Hi, I'm doing an install roughly following this guide: http://www.gentoo.org/doc/en/gentoo-x86+raid+lvm2-quickinstall.xml Differences: 1) AMD64 2) A non-RAID Gentoo install already resides /dev/sda 3) I'm doing the RAID install on /dev/sdb3 /dev/sdc3 4) RAID1 only 5) No LVM 6) Shared /boot grub 7) grub not installed for the RAID installation as I am using the non-raid grub to boot options The install is complete but it won't boot. grub finds the kernel and starts booting but then I get the typical VFS file sync error as the kernel starts looking for the install on /dev/md3. What I'm not understanding is how does the boot process get the information required to assemble the RAID device. By hand in the non-RAID install I do this: keeper ~ # mdadm -A /dev/md3 /dev/sdb3 /dev/sdc3 mdadm: /dev/md3 has been started with 2 drives. keeper ~ # cat /proc/mdstat Personalities : [raid1] md3 : active raid1 sdb3[0] sdc3[1] 52436092 blocks super 1.1 [2/2] [UU] unused devices: none keeper ~ # but when I try to boot the RAID install it says it cannot find /dev/md3. From within the non-RAID install I can mount md3. It's got the RAID install and I can chroot into it and continue doing install like things so all the data is there but I cannot boot it. I don't see what allows grub (I gruss) to start up mdadm, assemble the device and then continue the boot. What am I missing? grub.conf and fdisk info follows.

The problem is the kernel The kernel assembles RAID by looking for partitions of with the Linux RAID partition type, finding out what kind of RAID they are, and assembling them (according to their RAID volume UUID). You apparently only have one RAID volume. It's probably being assigned to /dev/md0, yet you are passing root=/dev/md3.. not sure why you are doing that.
Re: [gentoo-user] Disk or filesystem issue?
Probably neither. Can you Ctrl+F12 to see what the logs are saying? I've been getting kernel Oops! on shutdown on one machine of mine with the 2.6.31-gentoo-r10 kernel. Might be similar Ok, i found this, which is mentioning fglrx, and the problem may have started when i changed driver versions. So is it possible for an X driver to cause filesystem issues? I would have assumed not.

By hand in the non-RAID install I do this: keeper ~ # mdadm -A /dev/md3 /dev/sdb3 /dev/sdc3 mdadm: /dev/md3 has been started with 2 drives. keeper ~ # cat /proc/mdstat Personalities : [raid1] md3 : active raid1 sdb3[0] sdc3[1] 52436092 blocks super 1.1 [2/2] [UU] unused devices: none keeper ~ # but when I try to boot the RAID install it says it cannot find /dev/md3. You need to set the partition type for the RAIDed partitions to Linux raid autodetect. You'll probably then find that the kernel sets the RAID as /dev/md0, not md3. -- Neil Bothwick Tried changing root=/dev/md0. No change. The actual failure message is the fairly standard VFS - Unable to mount root fs on unknown-block(9,0) I can control this using (for instance) title /dev/sda1 Gentoo Linux 2.6.33-gentoo-RAID root (hd0,0) kernel (hd0,0)/boot/bzImage-2.6.33-gentoo-RAID root=/dev/md3 md=3,1,/dev/sdb3,/dev/sdc3 which changes the message to 'unknown-block(9,3)' Since the mknod command for md devices is always 9 1 or 9 3 those match up. Is this saying that the special file thing for 9,0 and 9,3 are missing at boot time? As I posted in the first post the partitions are marked as autodetect, but if it matters I did that late in the process after the RAID was built. keeper ~ # fdisk -l /dev/sdb /dev/sdc Disk /dev/sdb: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xa06ef201 Device Boot Start End Blocks Id System /dev/sdb1 1 14 112423+ 83 Linux /dev/sdb2 16 538 4200997+ 82 Linux swap / Solaris /dev/sdb3 544707152436160 fd Linux raid autodetect Disk /dev/sdc: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x2ab15637 Device Boot Start End Blocks Id System /dev/sdc1 1 14 112423+ 83 Linux /dev/sdc2 16 538 4200997+ 82 Linux swap / Solaris /dev/sdc3 544707152436160 fd Linux raid autodetect keeper ~ # Answering Albert - I did it with /dev/md3 because that's how the install guide did it: mknod /dev/md3 b 9 3 mdadm --create /dev/md3 --level=1 --raid-devices=2 /dev/sda3 /dev/sdb3 From fstab: /dev/md3 / ext3 noatime 0 1 From grub.conf: title Gentoo root (hd0,0) kernel /boot/kernel root=/dev/md3 Granted, my kernel line is a little different: root (hd0,0) kernel (hd0,0)/boot/bzImage-2.6.33-gentoo-RAID root=/dev/md3 but I didn't make it up.

The actual failure message is the fairly standard VFS - Unable to mount root fs on unknown-block(9,0) [snip] CONFIG_MD_RAID1=y That's all that needs to be enabled within the RAID section of the kernel. However, all the other options that would normally be required to boot must also be compiled in statically for things to work as expected (ATA/SCSI controller driver, filesystem of choice, CONFIG_BLK_DEV_SD and so forth). It seems that you may have overlooked something. However, it's impossible to determine whether that's the case based on the information presented thus far. I would suggest that you double-check your .config in full, or present it here for review, along with the output of lspci -nn. Cheers, --Kerin
[gentoo-user] Checking sanity of system...
Hi, this is no security issue in sense of attacks...it is related to the consistency of the system. Simple question (and may be complicate to answer... ;) ) How can I check, that my Gentoo system is uptodate, consistent and sane?
