Kernel compile problem
Hi all, I am having a problem when I re-compile my kernel (in Gentoo 1.2). When I run make menuconfig, I can see that Keyboard Support is enabled in Input Core Support, but after I do make dep clean bzImage modules modules_install and copy bzImage to /boot, when I reboot, the kernel doesn't see my keyboard. I can't do dmesg, because I can't type anything, but I noticed during bootup that a message appears saying something like AT keyboard not present(ed). Does anyone have any idea what I am doing wrong? Is there some other option I need to enable (or disable) so that my keyboard is recognized?

You don't ** have ** to have a software like ghost to do it. As long as you keep symbolic links symbolic, device files as device files and the permissions then you can copy the entire system to a new disk and that disk will be able to function as an operating system. A few issues: 0. When trying to revive a system from backup you will have to rerun your lilo (if you are using lilo). If you are using grub then you are better off since if the path to your kernel didn't change you will still be able to boot using the old MBR. When using lilo you will *** HAVE *** to rerun lilo (the lilo MBR contains absolute location (in terms of disk physical attributes) of the kernel which has probably changed). 1. There is no need to backup the system itself over and over. If you define a strict policy of separation between the program/data that you install/collect and the system installed programs/data then you can only backup your data (will save a lot of useless backup space). Also keeping all RPMS/.debs that you upgraded on the side is a good practice. 2. There are many backup packages for linux out there. Pick one. I like amanda because it(she ?!?) sends nice emails...:). Most of these know how to preserve all relevant file system information. If you are using more modern file systems with extra info (like access control lists etc...) then pick a backup software that knows how to handle those. These issues are more tricky and you'll have to check for every feature seperately. I advise you not to use those features unless you really need those since backup software support for those is still in the making in some backup packages. Cheers, Mark Erez __ Do you Yahoo!?

Re: System Backups
Quoting Erez Boym, from the post of Mon, 14 Oct: Hi, What would be the way to backup an entire system ? depends on your needs. how often you expect to use it, how expensive should the medias be, how many backups do you rotate, etc. you could do a full ghost with a tool called Partition Image, you can use the commercial tools from Norton and PowerQuest. you can rsync once in a while to a remote computer with cheap IDE disks, you can rsync to a local RAID of cheap IDE, you can backup to tapes with tools like AMANDA, you can backup to CDR/DVD-RAM with AMANDA+cdbackup, and there are many more options. then ofcourse there are the bigger enterprise solutions like backupExec, or lower-end commercial ones like BRU. bottom line: depends on your budget and needs. for what I read you described, here's what I think: 1. do a ghost of the server to a cheap disk, maybe using Partition Image (never tested it myself) 2. do a weekly full backup with rsync/tar (depending on the disk space you can afford) to a remote machine, and a daily level 1 (read the manuals of tar and AMANDA for more scenario ideas). that was you can survive a full crash, or just rescue a single file if something gets deleted or changed. 3. if you need a snapshot system like in NetAppliance look at EVMS or LVM. if you prefer the EMC-style, look at the linux MD option with RAID1 disconnection tricks. (though I think EVMS does that too, and more inteligently) 4. B/U is not a small question in any way.

Re: System Backups
There are a number of ways you can go about backing up your system, depending on what type of backup media you have available. The restoration procedure would depend on the backup method. It would be entirely possible to simply copy the file system onto a DVD (or a number of DVDs, depending of the file system size, and then to restore the file system from that by using some kind of rescue disk to boot with and then copying over the files. In order for it to work though, you would have to make sure that ownerships, file permissions, and file-links are preserved when you create the backup. You would have to re-install lilo after doing this if you use the lilo boot-loader (This might or might not be necessary if you use GRUB depending on what you did to the boot sectors and if you moved Linux to a different partition). Since I only have a CD-RW to back up my system, I use a program called Mondo backup to get the job done. It will compress files before they are written onto the disks and can have a backup span many disks. It also has built-in restore functions and can be used for DVDs too Yossi On Mon, 2002-10-14 at 07:37, Erez Boym wrote: Hi, What would be the way to backup an entire system ?

Since this question bothers me too, can anybody summarize the advantages of a dedicated backup software? A dumb copy can be used (if you pass the right flags to copy or to tar). Advantages/disadvantages: 1. a backup software usually registers itself as a cron process. You don't have to actually write the script or register it in cron. 2. a backup software is usually incremental. Meaning you can always have a snapshot of last night and not waste the entire disk space every night. The backup software only backs us all change since level 0 (full last backup). 3. a backup software sends you nice emails that predict when you will run out of space on your backup media so you can change it before hand. A script does not. 4. a backup software requires some learning (not a lot though and some have graphical front ends which are really easy). 5. a backup software keeps dates on files automatically. This means that you can save years of backups and not worry about organizing the files yourself according to dates (the backup software does it for you). This is all I could think of.

ObNote: block-block as backup, and especially dump are a bad idea compared to file serializers such as tar and cpio. moreover dump is not supported anymore in kernel 2.4!! other than the fact dump is OS and FS specific, there are apperently major problems with using it on 2.4 with all it's caching features, and I'd imagine journaling filesystems make it even more problematic. read this from Linus: http://old.lwn.net/2001/0503/a/lt-dump.php3 AMANDA warns about this too (scroll to about the middle of the page) http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/amanda/amanda-2/docs/SYSTEM.NOTES ?rev=1.48content-type=text/vnd.viewcvs-markup -- Born Yesterday Ira Abramov http://ira.abramov.org/email/ This post is encrypted twice with ROT-13.

Newer HDDs with ATA100/133 controller should be much faster. You can see the transfer speed by reading /proc/mdstat when you rebuild the array. BTW - I noticed that when the machine shuts down uncleanly it's automatically starting to rebuild the whole array, even if no data was changed. Isn't there a faster way to sync them?

I used the same configuration and it took about an hour+ to sync four
partitions with a total of 36Gb.

Speeding up flash access
Hello I'm using flash with JFFS2 on it. Well, its terribly slow and I'm looking a way to speed it up. What options do I have ? Using RAM drive and copying the whole filesystem on boot to it ? Using tmpfs filesystem ? Something else ?

you can purch a Mylex AcceleRAID 170 its somewhat expensive as its scsi and the disks need to be scsi too :) maybe there are some good ide raid card out there. any one tried such card ? - Original Message - From: Gabor Szabo [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, October 14, 2002 4:48 PM Subject: speed of RAID1 rebuild [was Re: System Backups] On Mon, 14 Oct 2002, Ira Abramov wrote: What if you setup two disks in RAID1 and pull one of the disks for backup and insert new one instead? 2. you will need to rebuild the mirror once it is reintegrated and thæt is a slow and painful process. how slow is it really ?

Using RAM drive and copying the whole filesystem on boot to it ? Using tmpfs filesystem ? Something else ? A wise combination of tmpfs and cramfs is the best solution IMHO. For those not in the know tmpfs is a 'virtual' file system - the files created on it do not exist on disk. Same idea as a RAM disk, but on the file system layer, not the block device. This provides many nice advantages (like memory consumption that adapts to file usage. The ramfs file system is the exact same idea but a more limited implmentation. I recomend using tmpfs for anything you would think of using ramfs. One thing to be aware of - you need to have 'tmpfs' compiled in the kernel for mounting it (so far no big news...) BUT be aware that even if you *do not* choose to compile it into the kernel it will still be included because it is used internally by the shared memory part of the virtual memory subsystem (aka VM). The trick is that when it is used in that fashion it is marked 'unmountable' (actually some parts of the filesystem are not compiled in when compiled in this fashion) but the name of the filesystem still shows up in /proc/filesystems which could be very confusing. Only if you also have an entry for 'shm' is the filesystem actually compiled for general use. cramfs is a compressed, decompress on the fly read-only file system (don't be confused by the 'ram' in the name). The idea is that you have a compressed image of the file system that you mount using loopback device, and everytime yoyu use a (page of a) file for the first time it decompresses to ram. Thus, space is saved on the storage device (flash) because the fs is compressed and at the same time precious RAM is saved because only pages that are being accessed are decompressed, not the entire file system/block device as would be the case with tmpfs/RAM disk You can use it as a root filesystem using the black magic of the 'initrd' option. Suggested usage - Boot into a timy initrd RAM disk image, from it choose an apropriate cramfs compressed image to loopback mount as root (you can support different software version for your application by choosing different images - cool, no? :-), copy from a specific location all files that needs to be read-write to a tmpfs filesystem and terminate the initrd phase continuing the boot.
