Re: [CentOS] Convert bare partition to RAID1 / mdadm?
From: Benjamin Smith li...@benjamindsmith.com Thanks for your feedback - it's advice I would have given myself just a few years ago. We have *literally* in the range of one hundred million small PDF documents. The simple command find /path/to/data /dev/null takes between 1 and 2 days, system load depending. We had to give up on rsync for backups in this context a while ago - we just couldn't get a daily backup more often then about 2x per week. What about: 1. Setup inotify (no idea how it would behave with your millions of files) 2. One big rsync 3. Bring it down and copy the few modified files reported by inotify. Or lsyncd?

Re: [CentOS] Convert bare partition to RAID1 / mdadm?
How about something like this: Use find to process each file with a script that does something like this: if foo not soft link : if foo open for output (lsof?) : add foo to todo list else : make foo read-only if foo open for output : add foo to todo list restore foo's permissions else : copy foo to raid replace original with a soft link into raid give copy correct permissions move the todo list to where it will not be written the script process the todo list files with the same script making a new todo list rinse and repeat until the todo list is empty for the endgame, make the entire source read-only run find again, this time there is no need for most of the tests: if foo not soft link : copy foo to raid replace original with a soft link into raid give copy correct permissions after the last copy, make the entire source unreadable and unwriteable wait for last user to close file rename the old files' top directory rename the raid's top directory let users back in -- Michael henne...@web.cs.ndsu.nodak.edu SCSI is NOT magic.

Re: [CentOS] attempting to create directory /root/perl5
Nobody seemed to answer, so I will answer it myself. If you have package perl-homedir installed, it adds its stuff to /etc/profile.d, and upon user login an existence of ~/perl5 will be checked and this directory will be created if it doesn't exist. It looks like perl-homedir appears in one of the package groups on CentOS 7. If (like me) you don't like this, you can add to your kickstart file line that will make this package excluded. Here are two lines I have at the end of %packages group in my kickstart file: %packages ... -perl-local-lib -perl-homedir %end Thanks.

Re: [CentOS] attempting to create directory /root/perl5
I'm not seeing that on my system. Assuming that your bash rpm verifies (meaning that nothing has modified the bash startup scripts), my best guess would be that some package has dropped a file into /etc/profile.d that creates the directory. Finding that file would be a first step on figuring out what it's trying to do.

It would seem technically quite feasible to reshuffle the partition a bit to make this happen with a special tool (perhaps offline for a bit - you'd only have to manage something less than a single MB of data) but I'm guessing nobody has felt the itch to make such a tool. In thinking about this some more, I had an idea that (a) I'm not totally sure would work, and (b) strikes me as dangerous. 1. Use dmsetup to create a logical device that consists of an 8 KiB prefix followed by your existing partition with the ext4 filesystem. 2. Create your RAID1 array using the above logical device as the first member and with the second member missing. 3. Unmount the current filesystem and mount the RAID device in its place. 4. Add a new device to the (currently degraded) RAID array, and let the RAID system spend the next couple of days recovering data onto the new device. Eventually, you would remove the dmsetup device from the RAID array and add a new device in its place. I have a feeling you will not want to risk your data to the above procedure. ;-) Trying to reboot a system with that cobbled together RAID member might prove an interesting exercise. -- Bob Nichols NOSPAM is really part of my email address.

Re: [CentOS] Convert bare partition to RAID1 / mdadm?
rsync breaks silently or sometimes noisily on big directory/file structures. It depends on how the OP's files are distributed. We organised our files in a client/year/month/day and run a number of rsyncs on separate parts of the hierarchy. Older stuff doesn't need to be rsynced but gets backed up every so often. But it depends whether or not the OP's data is arranged so that he could do something like that.
