Linux agent for True Image: snapapi DKMS/linux source problem

[redlex]

I'm trying to install the Linux agent for TrueImage. During install (running as root), I get the message:

I've tried updating the kernel and installing the kernel-devel package (by running "yum update kernel kernel-devel" then rebooting), as this seemed like it might help, but no dice, I still get the same error.
So I take it I need the full kernel source installed? Or do I need to get snapapi26.ko located in the DKMS tree (however that is done)? Or both?

I've seen posts about almost identical problems here on the board, but the information didn't help me resolve this...

thanks for reading!

Ok, I've downloaded the kernel source and put it in the correct place.
I get further this time, but compiling snapapi fails:

Any ideas anyone? SLAB_ATOMIC obviously causing problems, but can't get much further than that....

[AaronAnderson]

What OS / verison are you using?

See my howto for Ubuntu / Debian

http://www.wilderssecurity.com/showthread.php?t=173463

[redlex]

Hi Aaron
Sorry, I forgot to say: Fedora Core 5.
And yes, you have hit the nail on the head: installing snapapi (with the DKMS stuff) is the problem, I think.

[redlex]

Here's another little query about compiling snapapi...

I am using FC5 and according to http://docs.fedoraproject.org/release-notes/fc5/:

----8<----
8.7. Preparing for Kernel Development

Fedora Core does not include the kernel-source package provided by older versions since only the kernel-devel package is required now to build external modules. Configured sources are available, as described in this kernel flavors section.
----8<----

Am I right in thinking that the kernel-devel package will be enough to compile snapapi, and that I don't need the full kernel source for FC5?

[redlex]

Hi all
Think I've almost got it, what I'm doing is similar to what everyone else is doing now - I've installed Acronis package on FC5 /without/ installing snapapi, then am attempting to compile snapapi using dkms using the following command:

dkms build -m snapapi26 -v 0.7.10 --config /boot/config-2.6.20-1.2316.fc5 --arch i686 --kernelsourcedir /usr/src/kernels/2.6.20-1.2316.fc5-i686

(Above command has been customized for my exact system, I've not just copied this blindly from elsewhere!)

The output I get is:


Preparing kernel 2.6.20-1.2316.fc5 for module build:

Consult the make.log in the build directory

... and the above-mentioned make.log file contains:

Before doing all this, I updated the kernel to latest and installed kernel-dev package and rebooted, so I have a current kernel (and kernel dev headers).
Any ideas anyone?

[redlex]

Resolved. Support got in touch and pointed me at a newer rpm for snapapi whichsorted things out (as described by others here). Thanks!

[RobMac]

hi redlex,

I am getting the exact same errors running dkms. Where is the updated snapapi rpm that fixed it for you? Is there a public link?

thanks,

Rob

Hello RobMac,

Thank you for choosing Acronis Disk Backup Software (http://www.acronis.com/enterprise/products/).

Please follow the link AaronAnderson provided for instructions on how to obtain the updated snapapi rpm.

Thank you.

I think you should install basic compile environment firstly.
If you use ubuntu 6.06,you can run this command:
Code:
sudo apt-get install build-essential
::)

[99problems]

I am useing Fedora Core 6 and receiving the exact same errors as Redlex above.

Can someone explain how to install the latest snapapi rpm. I have received snapapi26_modules-0.7.19-2.noarch.rpm from support and I installed it:

rpm -Uvh snapapi26_modules-0.7.19-2.noarch.rpm
Preparing... ########################################### [100%]
1:snapapi26_modules ########################################### [100%]

Uninstall of Acronis SnapAPI Linux kernel 2.6 modules (version 0.7.10):
ERROR: Module snapapi26 does not exist in /proc/modules
ERROR: Module snumbd26 does not exist in /proc/modules

------------------------------
Deleting module version: 0.7.10
completely from the DKMS tree.
------------------------------
Done.

Now there is nothing but 1 file in /var/lib/dkms
dkms_dbversion

The snapapi26-0.7.10 directory is still in /usr/src

There is no snapapi26-0.7.19 anywhere

The only reference I see to .19 is /usr/lib/Acronis/kernel_modules/snapapi26-0.7.19-all.tar.gz

The tar file has main tree which is emtpy and source tree. I copied the files of the source tree to /usr/src/snapapi26-0.7.19 to mirror the .10 tree.

When I run the build command I receieve:
Error! DKMS tree does not contain: snapapi26-0.7.19
Build cannot continue without the proper tree.

Any help would be appreciated, thanks!!

[Acronis Support]

Hello 99problems,

Thank you for choosing Acronis Linux Server Disk Backup Software (http://www.acronis.com/enterprise/products/ATISLin/).

Please note that after installing the downloaded package (snapapi26_modules-0.7.17-1.noarch.rpm) you should load the module tarball to DKMS:

#dkms ldtarball --archive=/usr/lib/Acronis/kernel_modules/snapapi26-0.7.17-all.tar.gz

Then build and install the new module:

#dkms build -m snapapi26 -v 0.7.17 \
-k <KERNEL_VERSRION> --config <CONFIG_FILE> --arch <KERNEL_ARCH> \
--kernelsourcedir <PATH_TO_KERNEL_SOURCES>
#dkms install -m snapapi26 -v 0.7.17 \
-k <KERNEL_VERSRION> --config <CONFIG_FILE> --arch <KERNEL_ARCH> \
--kernelsourcedir <PATH_TO_KERNEL_SOURCES>

Please make sure you provide the full path to the config file and to the kernel sources.

Thank you.

thank you!! this was the part i was missing.

[ibell]

Hi I was able to install the snapapi_module v 0.7.19

However I'm not able to run True Image, if i issue a command:

trueimagecmd --list

I get an error message, that a required module is missing please reinstall the program. Any ideas? I'm using Fedora Core 6 kernel version is: 2.6.20-1.2948.fc6

Thanks,
Seth

[ibell]

Also modprobe wont load it:

modprobe snapapi26
