Diagnostics from setup-storage
Hello! I tried installation of a multi-disk host with the latest experimental (version 45). With correct disk configuration file, everything works as expected. My thanks to Michael and everyone else for great work! However, before I got to the error-free state, I went through several incorrect ones and noticed that the diagnostics provided by setup-storage were not too helpful, and in one case, outright wrong. First, the final (correct) disk configuration file: --- snip - disk_config hda bootable:1 logical / 1GiB ext3 rw,relatime,errors=remount-ro createopts="-c -j" logical /var 10GiB ext3 rw,relatime createopts="-m 5 -j" logical /tmp1GiB ext3 rw createopts="-m 0 -j" logical /usr 10GiB ext3 rw,relatime createopts="-j" primary swap2GiB swap sw primary /home 10GiB ext3 rw,relatime,nosuid,nodevcreateopts="-m 1 -j" primary /wrk 10GiB- ext3 rw,relatime,nosuid,nodevcreateopts="-m 1 -j" disk_config sda preserve_always:all primary /storage 100% ext3 rw,relatime,nosuid,nodev,noexec disk_config sdb preserve_always:all primary /st_backup 100% ext3 rw,relatime,nosuid,nodev,noexec --- snip - Next, the two errors I made initally and the provided diagnostics: First, I had an unnecessary space between "rw," and "relatime" in the sda and sdb layouts, like this: primary /storage 100% ext3 rw, relatime,nosuid,nodev,noexec The only diagnostic provided by setup-storage was "Syntax error". I would have expected at least a line number, and possibly the column, where the parser hit the error. Without that, the error was not trivial to locate. Second, in my inital version I had duplicate configuration for disk sda (ie the /st_backup disk was also called "sda"): disk_config sda preserve_always:all primary /st_backup 100% ext3 rw,relatime,nosuid,nodev,noexec The diagnostic from setup-storage was: Use of uninitialized value $1 in subtraction (-) at /usr/share/fai/setup-storage//Parser.pm line 130, <$config_file> line 1. Duplicate configuration for disk sdb I see two issues here: 1) the first error is a perl message, not a setup-storage message 2) it complains about sdb being duplicate, while in reality it is sda. With more complicated multi-disk systems this can be quite confusing. Best wishes, Toomas Tamm

setup-storage fails when preserving LVM volume
Hello, When installing in Squeeze a host which was in Lenny, I want to preserve user data, using a setup-storage config that has worked with an older version of FAI (well, I'm not so sure, let's say it might have work some day...); the result is the same with 3.4.4, 3.4.5, and 4.0experimental45 : disk_config disk1 primary/boot 512ext3rw primary- 32000--- disk_config lvm fstabkey:uuid preserve_lazy:vg0-local vg vg0 disk1.2 vg0-swapswap2GiBswapsw vg0-root/ 1GiBext3rw vg0-var /var4GiBext3rw vg0-usr /usr8GiBext3rw vg0-opt /opt2GiBext3rw vg0-local /local 20GiBext3rw On an empty disk, this disk config works fine. But when the volumes already exist, it does preserve vg0-local as expected, but after having correctly built all the volumes setup-storage tries to set a label on the disk; it fails miserably, and removes all the disk's partitions . There are a couple of other errors in the debug log, too, that might be related to the problem: [...] Use of uninitialized value $p in concatenation (.) or string at /usr/share/fai/setup-storage//Init.pm line 289. /dev/sda2 will be preserved vg0/local will be preserved [...] (CMD) parted -s /dev/sda mklabel msdos 1> /tmp/A_p3dpsLFC 2> /tmp/ZQLJLH5omp Executing: parted -s /dev/sda mklabel msdos Command had non-zero exit code (STDOUT) Error: Partition(s) 2 on /dev/sda have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use. As a result, the old partition(s) will remain in use. You should reboot now before making further changes. I have tried to replace disk1 by sda, preserve_lazy by preserve_reinstall, but the result is always the same. The full log is there: http://paste.debian.net/101879/ -- Nicolas
