[gentoo-user] acroread-9.3.2 produces invalid postscript?
Hi, I have very bad experience with acroread-9.3.2. Some printers (claiming to support postscript level 3) just hang. When I first 'print' to a file, gv only shows some part of each page and evince just hangs. Has anybody similar experience? (Yes, I can use xpdf, but acroread has the nice feature of printing several pages on a sheet of paper which is very handy when printing slides of a presentation) Thanks, Helmut. -- Helmut Jarausch Lehrstuhl fuer Numerische Mathematik RWTH - Aachen University D 52056 Aachen, Germany

[gentoo-user] No /dev/sd? devices. Udev problem?
Hi there! I just migrated a friend's machine to ~am64. Everything was updated, but after a reboot some partitons are not found. No wonder, there are no /dev/sd? devices, only /dev/sg?. I suspect the problem is udev, because that was updated. Root is encrypted, so this machine makes use of an initramfs. At that point, all devices are found, so the system comes up, but later mounting of data partitions fails due to the missing devices. Any idea what the cause is? I will try to downgrade udev and see what happens. I have to wait for my friend to arrive here though, because I do not know the LUKS password. So I thought I'd ask here first, maybe someone knows this problem. Wonko
Re: [gentoo-user] backup to a cold-swap drive
Iain Buchanan writes: A winblows colleague said he uses a utility to backup his internal hard drive to an external disk, such that if his internal disk fails he can replace it with the external disk and continue straight away. I do the same, but with a 2nd internal drive. The drive is partitioned similar, with some partitions being a bit larger so I can do incremental backups, too. I am using rdiff-backup, which makes use of rsync. The backup partition has exactly the same contents as the source partition, except for an additional 'rdiff-backup' directory that contains incremental backups of files that were modified from backup to backup, gzipped. Some other partitions are handled differently: /boot is just being dd'ed, contents of /usr/src are tarred each, and /var/portage/packages/ is just plain rsynced. Some unnecessary stuff like .ccache and /var/tmp/portage is excluded. All my partitions are LVM volumes, so before the backup starts, I make a LVM snapshot of the partition. This way I can modify it while the backup is still in progress. I wrote a shell script to do this, so I do not have to issue a lot of commands every time I want to do the backup. As there are now some others using this script, adapted to their needs, I started to rewrite it in a way that it reads a config file, and no modification of the script itself is necessary. If anyone is interested, send me an email. Some time ago my first drive started having bad blocks. Without LVM, I could just have swapped the disks, but so I had to rename the backup volume group to the original volume group from a live cd. And the system was running from the new drive as it was before - only that I no longer had a backup until the new drive arrived. This makes an uneasy feeling with these 1.5 TB drives. Wonko

[gentoo-user] Re: Print server with hplip
I've been using a print and scan server with an Epson printer/scanner for a long time. I'm trying to set up the same thing with an HP and I've got everything working except remote printing. Local printing, local scanning and remote scanning work, but not remote printing. I have the client's IP in /etc/cups/cupsd.conf and the server's IP in /etc/cups/client.conf but the client won't pick up the server's HP for printing. Could there be any extra configuration required for remote printing when switching from gutenprint (I think) to hplip? I had to add saned to the lp group on the server before I could get remote scanning to work (not required with the Epson), and I'm wondering if there could be a similar detail I'm overlooking with remote printing. - Grant I guess hplip uses something called JetDirect for network printing. hplip in general seems to want to do things its own way. I don't think I'll bother with it. I'm going to get rid of this HP and get an Epson anyway since scan quality is sub-par. - Grant

Other than that the only thing I can think of is something like a performance regression in the ide/scsi/sata controller (on host or virtual) or mdadm on host. If the host system is bogged before starting vmware instances I would suspect the former (host controller or mdadm). The disks look good so far ... Just to bump this one up again ... Hard disks OK, ran long smart-tests, completely ok. Still that high io-load from kdmflush. No change since then. What do you guys use? RAID1, RAID0 ?? LVM? Specific filesystems?

[gentoo-user] Is my data gone?
While setting up a new disk I accidentally ran mke2fs /dev/sda1 instead of mke2fs /dev/hda1. When I realized the mistake (about 2 seconds later) I hit Ctrl-C before mke2fs was done. Now I can't mount the drive. Is there a way to read the drive to get the data off or is it unrecoverable? Thanks, dhk

Most of the data was stuff I finished and was trying to decide what to do with, guess that decision's been made. Hopefully I'll never have to recreate them. Anyway to pick up the disk from the middle? I really don't want to go through the tapes and download them again. Thanks, dhk

Before attempting anything I would clone the drive to a spare and then attempt recovery on the clone. (because sometimes trying to fix it can just make things worse). You can try something like testdisk, and of course try fsck first. Or one of many commercial programs such as those listed here which probably do the same thing as testdisk: http://unformat-ext2.qarchive.org/ There's no simple unformat command or anything that I know of, though.
