Re: [BackupPC-users] How to move backuppc data from lvm to bigger disks/lvm?

I did upgrade an other server which had no lvm volume a feew weeks ago. This was easy, I just copied the reiserfs partition to the new system with dd an netcat and resized/grow the partition afterwards. What is the best way to do this with lvm? I have attached 2 external USB disks (500GB+ 300GB = 800GB with lvm) as a temp. storage for the old data, because the 4 on-board SATA ports are all used by the old backuppc data. I'm not sure if I can just dd the old lvm volume to one big file on the USB disk, replace the disks, dd the file back to the lvm volume and resize the reiserfs fs? dd if=/dev/mapper/VolGroup00-LogVol00 bs=8192 of=backuppc.dump ..replace disks, create new lvm volume... dd if=backuppc.dump of=/dev/mapper/bigger-lvm-volume bs=8192 I think the dd data includes information about the lvm volume/logical groups. I guess A lvm snapshot will not help much. I think if you do that, you will have problems.. I would do this: stop backuppc and unmount the filesystem (or mount readonly) resize the reiserfs filesystem to 800G I already tried this, but resize_reiserfs gives me an bitmap error. I realized that my first idea with dd and the backuppc.dump file will need a additional gzip command to work, because the destiantion fs is smaller than the source. resize the LVM partition to 800G dd the LVM partition containing the reiserfs filesystem to your spare LVM partition replace the 4 internal HDD's create the new LVM / RAID/etc setup on the new drives dd the USB LVM partition onto the internal LVM partition you have configured resize the reiserfs filesystem to fill the new LVM partition size Because resize_reiserfs is not working, this is no option :( I don't promise it will work, but if it doesn't, you do at least still have your original drives with all the data, The problem I see in your suggestion is that you are copying a 1TB filesystem/partition into a 800GB one therefore if you have stored data at the end of the drive, then it will be lost, the above should solve that problem. At the moment I'm transfering the data with cp, but in the last 12 hours only 50% of the data (~380GB) were copied. And this is only the cpool directory. But this is what I expected with cp. I thought about an other fancy way... * remove the existing volg/lv data on the usb disks * use vgextend to expand the existing backuppc volg with the 2 usb disks * pvmove the data from 3 of the 4 old disks to the usb disks * remove the 3 old disks with vgreduce * replace 3 of the 4 disks with the new ones * create a raid 5 with 3 new disk (3x 500GB = 1TB) * create a new pv on the raid * expand the backuppc volg with vgextend * pvmove the last old disk and the usb disks to the raid pv * remove the last old disk + usb disks with vgreduce * replace the last old disk with the new one * grow the raid 5 (this is possible since kernel 2.6.17 or so...) * pvresize the raid 5 pv Sounds like a lot of fun ;) Ralf - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

I'd recommend manually running the smbclient command and pipe the output into tar tvf - so you can see how far it gets and perhaps where it hangs. You might try running WinXX chkdsk on the client. You might also try disabling your AV software to see if that makes a difference.

[...] The problem I see in your suggestion is that you are copying a 1TB filesystem/partition into a 800GB one therefore if you have stored data at the end of the drive, then it will be lost, the above should solve that problem. just to make it clearer: the device file name /dev/mapper/VolGroup00-LogVol00 means you have not been very imaginative when choosing VG and LV names, but aside from that, it That's true, but with only one volg/lv I didn't care much about it. represents a plain block device. The filesystem is not and should not be aware of how the underlying block device is implemented. Reading /dev/mapper/VolGroup00-LogVol00 gives you the concatenation of the raw blocks it consists of in ascending order, just like reading /dev/sda1, /dev/sda, /dev/fd0 or /dev/sr0 does (/dev/sr0 is likely not writable though) - nothing more and nothing less. Meta-information about VG and LVs is stored in the PVs outside the data allocated to any LV. Ok, then dd if=/dev/VolGroup00/LogVol00 bs=8192 | gzip -2 -c backuppc.dump.gz gzip -dc backuppc.dump.gz | dd of=/dev/fancy-vg-name/fancy-lv-name should work. I created a file with 'dd if=/dev/zero of=/var/lib/backuppc/null' this should help compressing the unused space better. I agree that you will need at least as much space as your LV takes up if you want to copy it. I would add that copying into a file will probably give you more trouble than copying to a block device (provided it is large enough). There's simply one layer less of arbitrary file size limits you would be dealing with. Yeah, last time I did this on an other system I was able to use resize_reiserfs and it worked very well. I've no idea why resize_reiserfs is now giving me this bitmap error.

Re: [BackupPC-users] How to extract information on duplicate files from BackupPC
You might consider fslint It is designed specifically for this task.

I'd like to eliminate duplicate files on my system, and since BackupPC has already gone to the work of identifying them, I'd like to get some sort of report listing the paths (relative to the original system(s)) to the duplicated files I've looked in the documentation and searched the mail list archives, but haven't found this. My apologies if this has been covered before; feel free to point me to the appropriate URL if so. You need to find all the files with same inode. You can do that with find, but that is expensive. Three years ago Yaroslav Halchenko reported that he had modified the linux locate tool to also save the inode in its database. That allows very fast lookups via inode (after the fixed overhead of crawling the tree to update the locate db).

[BackupPC-users] Automating windows clients installation
Hi guys I am using backuppc with success for at least 3 years, I backup mostly linux servers, but also have some windows hosts. Some of these linux machines are through a VPN, using openVPN. Now I am thinking about backing up some disperse Windows hosts using the Internet as the network, with the backuppc server in a safe place. The idea is that the amount of data on each machine will be something like 100-200MB. One of the problems I see are the difficulties related to installing and configuring OpenVPN on windows, configure the samba shares, and backuppc. Although this is not a very very hard problem, it is for final users. My idea is to build a sort of installer for this situation, which with a few questions would do the job. But I don't have any experience with this kind of thing in the windows world. I believe it could be done with Inno Setup (http://www.jrsoftware.org/isinfo.php), which seems to be a nice program, but I never used it. Do you think it is a good idea to implement this sort of thing? The main question seems to be: Is this sort of thing already available?

[BackupPC-users] Cygwin, Rsyncd running slow
Hi, I am setting up my first rsyncd/cygwin backup of a windows client. The client has 60GB of data on it and it currently takes 23 hours for a full backup (100MB link between the client and the server). I thought the problem may the size and number of files with rsync so I split it into 3 backups of roughly 20GB each and it is still just as slow. Any ideas on how to speed this up or figure out where the slowdown is are most appreciated. cheers, ski -- When we try to pick out anything by itself, we find it connected to the entire universeJohn Muir Chris Ski Kacoroski, [EMAIL PROTECTED], 206-501-9803 - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

One thing I noticed is that my anti-virus program would do a virus scan during the initial rsync search to build the list of files, and I assume again while it was actually transferring the changed files. Turning off the AV would significantly decrease the time for rsyncd to build the file list.
