Aquileo | #5 insertionops.cc:36:36: error: const struct ext2_inode has no member named i_dir_acl

2022-04-15T15:31:01.024000Z

To resolve this error, clarification why this needed, I found the solution detailed here https://sourceforge.net/p/ext4magic/tickets/10/

"The upstream has removed the macro that defined i_dir_acl as i_size_high which causes a build failure with the later versions of e2fsprogs. Replace every reference to inode->i_dir_acl with
inode->i_size_high."

Aquileo | A scenario not covered - needs improvement

2021-06-21T05:32:46.219000Z

Deleted a directory by mistake on an ext4 partition. Tried TestDisk (doesn't find anything, as expected). Tried extundelete, surprisingly, it did not find the deleted directory either.
Went to R-Studio and used their tool (demo ISO, free tool too), those find the deleted directory and restore the files, including their names.

From this, as long as the file names were restored, as the information still exists in such case, I deduce that extundelete should find them too, but fails for some reason I can't tell. Can it be improved for such simple scenario?

As usual? Checkout or unpack source code, apply patch with patch command (patch -p1 < /path/to/patch) and compile it (./configure, make, make install)?

How can I use this patch?

Thank you, this enabled me to recover the deleted files from my sons laptop.

With newer e2progs, compilation will fail.

Attached patch fixes it.

Aquileo | CentOS7 64Bit rpm crash Error in `extundelete': double free or corruption (!prev): 0x0000000000ae0fa0 ***

2018-03-04T22:49:09.992000Z

Hello,
thanks for greating this nice peace of software.

it is THE reason why i still prefer ext3 over ext4 X-D (while ext4 being atleast 10% faster... who cares about speed if you can't recover files that got deleted by a mad command)

i tested it with the latest (2018-03-04) available kernel under CentOS7 while there is no official *.rpm build available i used this one: http://ftp.tu-chemnitz.de/pub/linux/dag/redhat/el7/en/x86_64/rpmforge/RPMS/foremost-1.5.7-1.el7.rf.x86_64.rpm

which installed fine... but was not able to extundelete a 5TB large RAID10 with ext4, ext3 worked well!

full error message her:

... i stick to ext3... i just hope it survives 2030 X-D

Aquileo | Ability to exclude files when restoring whole directories.

2016-12-16T01:23:06.577000Z

I have a a huge amount of data (all of /home) that was deleted, but most of it is in only four files, and I don’t need these four huge files. Whose names I know. I only need all the little files. Whose names I do not know.

With extundelete, I can only recover the whole directory. Unfortunately I have no way of storing the whole directory. (In my case, all I have is a LiveDVD. No other removable media. Nothing. I am currently forced to use sshfs, but the connection can only do 100kB/s, and is disconnected every 24h. Which, when inluding those four huge files, is not even close to enough.
This means that after 24h, I have to reconnect sshfs (actually twice) and restart extundelete. Which means it will start from the beginning. And hence I will already know that the same thing will happen again.
I tried separating by date. But they were nearly all originally copied in the span of about 2 minutes. So that unless it hit it to a few seconds, there is no way to separate it in a way that is useful. Since I can’t find out the original date of those huge files, I can’t do it.
You see, it’s a mess.

And an exclude function, like in rsync (but in any case allowing one to specify more than one file), would make this an easy and quick thing. Such a function would also generally be very useful.

So… can you add such a function? That would be awesome.

Aquileo | extundelete.cc:1435: pointless allocation ?

2015-11-23T13:47:49.912000Z

[extundelete.cc:1435]: (style) Variable 'buf2' is allocated memory that is never used.

Source code is

char *buf2 = new char[ EXT2_BLOCK_SIZE(fs->super)];

Aquileo | feature request: restore files/folders/anything that had space reallocated

2015-03-18T15:33:20.546000Z

I deleted some 300MB folder and almost instantly ran extundelete. Thus the data was if then only corrupted to a minor degree and can largely be rescued.
