Hi :) I'm new to the list. I already received some hints from another Arch Linux mailing list. Sorry that my mail is formatted in HTML. When I tied to restore the distro I used before from a backup for the billionth time, I made a mistake and accidentally deleted originals and backups from ext4 partitions. Currently I'm even unable to boot any from my other Linux installs, so I'm using a Parted Magic live CD, resp. the web mailing thingy from my provider. I'll switch to Arch Linux because for my needs, audio productions, it could be easier to keep it stable than it is for other distros. I've got two questions. 1. What is a safe FS, that can be recovered? Ext4 seemingly isn't such a FS. The FS also should be usable for audio productions. Security regarding to multiple user usage, web access, server usage etc. are unimportant for a DAW. 2. For my main Linux I always prefer to use 64-bit architecture, but 32-bit architecture compatibility is needed. Is there something I should take care about when installing Arch Linux? Cheers! Ralf

No idea about the filesystems but on 32-bit architecture, you shouldn't have any problems. Arch is using a different repository for 32-bit software under 64-bit machines called 'multilib'. You only need to enable that and you will be fine. On 6 December 2011 15:08, Ralf Mardorf wrote:

Also not true. There is real hardware RAID, BIOS "fakeraid" and software RAID. The first one is expensive. The last two require setup inside Arch.

It is true that ext3 has existed for longer than ext4. However, most testing is now probably done on ext4, so I wouldn't expect ext4 to be more buggy than ext3. The real difference is that ext4 allows you to mount your partitions with optimizations that might cause more dataloss on a powerfailure than what the standard ext3 options would. I'd rather change the mount options for ext4 than move to ext3. Cheers, Tom

Generally, running 'rm' on a file means it's gone. It's the specification of 'rm'. Expecting something different means you're doing something wrong. If you want to undelete, you need some kind of log-based filesystem with rollback support. None of the ext* family can do that, and never could. The ext3/4 undelete tools are hacks, based on luck.

Sort of, more so on SSDs but it's just harder to reconstruct because SSDs writes are spread out as sectors get worn out much quicker. For speed, /bin/rm just removes the reference in the partition table which is why it takes ages to write but a second to delete, leaving the data and allowing it to be overwritten later which could be in a second or possibly never. It is less likely to be overwritten on unix with partitions and a dedicated swap rather than on windows with a growing pagefile. The only rm command that makes the data gone that I know of is OpenBSDs rm with option -P, which overwrites 3 times.

I'm not talking about implementation, but about specification. There is no guarantee that the file is gone, and there is also no guarantee that it can be recovered. If you run 'rm', you should expect the file to be gone for good - because that is what can happen according to the specification. Re: SSDs: File systems like ext4 can run discard commands that will tell the SSD firmware that the data is no longer needed - so even though the data is still there, the place on the SSD where the data resides is no longer associated with the logical "block" where they were. If you read that block, the SSD firmware may simply return a bunch of zeroes. Recovering data in this case requires raw access to the flash memory itself (which modern SSDs won't grant you).

When you delete something from a filesystem then you should expect it to be gone, it will only be recoverable by chance or luck. Ext4 is an evolution of ext3 so recovering deleted files shouldn't be much different, on the other hand, day to day usage can benefit from using ext4 over ext3. Give testdisk a try, it might not be able to recover everything though, depending on what you've done to the fs after you deleted the files. -- Mauro Santos

Somebody asked what happened. As root I wanted to run rm -r /media/path/to/a/partition I made 2 typos, one of the typos was a space behind /media rm -r /media /path/to/a/partition When I noticed the space I directly pushed Ctrl+C, but my SATA drives seem to be very fast. After that accident I directly remounted the drives to read only, all recovery trials should be done read only too.

This is not safe to do anyway. If I understand you well you were trying to remove an empty folder that was a mount point before ? Then use "rmdir" instead of "rm -r". It will accept to remove the directory only if empty which is the safe behavior you want in that case. +++ Thank you Cédric :) I didn't know rmdir. I need to correct myself it was rm -r /media/path/to/a/folder to delete the contend of a folder. In media there were two partitions mounted. One partition with backups and audio productions and another where I restored Debian from a backup that was some days old. After I restored Debian I wanted to delete /home and /user/src and then replace it from a younger backup. I should have remounted the backup partition read only. But my steps where, backup a broken Debian, restore Debian by an older backup and then get some data from the new backup. There might be sync commands that also avoid such mistakes, but I'm using tar, cp, rm, since sync commands need to much effort to learn the usage. ;) Ralf

rsync is indeed quite complex to master with all its options. But you may start from a safe basic set of options like "-av" and expand your knowledge as needed from here.

I can't imagine it'll be all that loud. i run a 2x2TB RAID1 (md/softraid) array for my local server using dense/"green" disks (5900rpm) and believe me, the disks are dwarfed by everything else (eg, fans ;-) your "mount one at a time" scheme won't really help you ... what if your disk dies since the last backup? RAID lets you replace a disk in real-time/on-line and gives a noticeable read performance boost ... what's too lose? off-site backups are still a good thing.

regardless of distro you'll just have to work it into youre needs. Arch will let you do this pretty well, but you'll just have to stay on top of incoming changes ... such is life i suppose :-) Pulseaudio works fantastic for the use cases it was designed for (which fulfills 95% of people's needs), but if it doesn't work for you, you can suspend it and let JACK or whatever take control as needed. -- C Anthony

A cinch with tools like testdisk unless it's been overwritten, in which case it would need to be worth >£1000 to recover it in a cleanroom. I always save copies of my documents as text too as text can be read and found as text on a disk, even fragments ;-).

Have you tried testdisk to recover the data. An arch package is available and it supports ext4. You shouldn't run the OS from the disk your recovering from as you may overwrite the lost data. This bootdisk comes with testdisk ready to go and won't touch your disk. http://www.sysresccd.org/ Kc

I already received some hints from another Arch Linux mailing list.

Welcome to Arch Linux :)

...

Sorry that my mail is formatted in HTML. When I tied to restore the distro I used before from a backup for the billionth time, I made a mistake and accidentally deleted originals and backups from ext4 partitions. Currently I'm even unable to boot any from my other Linux installs, so I'm using a Parted Magic live CD, resp. the web mailing thingy from my provider.

When I tell some people that I use plain text, I am made aware that it's already 2011 :D

...

I'll switch to Arch Linux because for my needs, audio productions, it could be easier to keep it stable than it is for other distros.

Here I'll give you just one page to read: https://wiki.archlinux.org/index.php/Pro_Audio

...

I've got two questions.

1. What is a safe FS, that can be recovered? Ext4 seemingly isn't such a FS. The FS also should be usable for audio productions. Security regarding to multiple user usage, web access, server usage etc. are unimportant for a DAW.

There are 3 things you're probably thinking or recalling. In the early days of ext4 there were some issues with data _loss_. That is not to be confused with intentional data _removal_. Either way, those early days are long gone, and I can't remember the last time I had actually lost data. In fact, this system has gone through harsh treatments including forced halts during intensive disk operations. Potent disaster, but I have not lost anything. The other issue is with regards to data _recovery_. Ext4 is by design a tad bit different from ext3, and any data recovery tool which can work with ext2/3 needs some additional work to support ext4 [1]. TestDisk can help with NTFS, FAT and ext2 for quick recovery of files for which metadata still exists, but not so with ext3 or ext4. For that, you'd need to "carve out" data. PhotoRec will get you the most relevant files, but you can take a look at Foremost if you want to recover even older ones. At the end of the day, however, as Thomas has mentioned, you can only hope. The last and probably least of your concerns is (or should be) whether the FS is suitable for audio production. Ext-based filesystems have the lowest latency, aside from JFS which beats them all. However, there is no empirical data to prove that this disk-level latency has any adverse effects on realtime audio/video in reality. You should purchase a fast HDD if disk latency is a concern at all. Better yet, get an SSD so you eliminate seek time entirely (best for sampling).

...

2. For my main Linux I always prefer to use 64-bit architecture, but 32-bit architecture compatibility is needed. Is there something I should take care about when installing Arch Linux?

Cheers!
