I think I messed up stuff here :-( My plan was to deliver also a 3.0.5 +
mindi 2.1.8 to solve some of the issuess that can be backported to that
branch. It will then be clean in that case. I didn't followed correctly
the process to publish 2.1.7 which is creating these problems.

Thanks a lot for these feedback. Encorages me to publish 3.2.0 sooner

Mondo 3.2.0 on Fedora 20 - problem with root VG in LVM-on-RAID

Hello everyone,

 

I am testing out Bruno's new 3.2.0 Fedora 20 packages from the test repo.

 

My kernel is 3.16.3-200.fc20.x86_64. Fedora 20 is installed on 2 x 64GB SSD. /boot is on Linux md RAID 1, everything else is in LVM on another Linux md RAID 1 and Grub 2 is installed on both devices.

 

DVD verification at the end of Mondoarchive passes OK but on booting in “compare” mode Mondo is unable to mount the LVM-on-RAID volumes. If I do the same on another otherwise similar Fedora 20 install but on a single disk (i.e. root VG still in LVM but no RAID) the mount list still shows zero size for the LVM volumes but can mount them OK and "compare" is happy - so looks like it is the Linux md RAID that is causing the problem.

 

Anyone have any suggestions? From searching around it looks like LVM-on-RAID configurations can be problematic. Since FC17 there has been a kernel panic on booting from a Mondo rescue disk; 3.2.0 fixes that so a big step forward as far as I am concerned!

 

Regards,

Andrew

other types of backup (tar)

Hello,

I have quick question regarding possible types of storing backup data via mondo.
Is it possible to save backup as *.tar files instead of *.iso? Maybe you can help with some hint how to achieve that?

Michal

HP ILO Virtual CD problem on restor

Hello,

I need your help on a problem with an HP DL580 G7 server. I have an error message when I try to restore my machine with ILO virtual CD
I'm running on Debian Jessie (3.14-2 kernel-amd64)
mondoarchive seems to be correct (the logs are attached)

I boot from the CD, and when mondo mount it (find-and-mount-cdrom) the media is not found. I have an error for each test (/dev/hd?, /dev/sr[1-9] ...)

is not a valid block device.

But for /dev/sr0 and /dev/scd0 I receive the following error:

No medium found

I conducted
recovery tests on HP EliteBook 8540w and it works fine (with the kernel 3.14-2-amd64), the cd is mounted on /dev/scd0 (burned cd)

Here is the status of my system at the time of the backup:

/etc/fstab

...
/ dev / sr1 / media / cdrom1 udf, iso9660 user, noauto 0 0
/ dev / sr0 / media / cdrom0 udf, iso9660 user, noauto 0 0

dmesg when I insert an ISO through ILO

I change find-and-mount-cdrom to test /dev/sg? (in addition to /dev/sr? and /dev/scd?) and it does not work


/usr/sbin/mindi

...
# Force To Be Some modules included
FORCE_MODS = "usb_storage usb_common nls_utf8 isofs nfs_acl nfs hpilo sr_mod usb_storage hid_generic ehci_hcd usbcore usbhid sd_mod ehci_pci uhci_hcd"
....

Mondoarchive method:

# mount nfs <NFS IP>:/share /share
# mondoarchive -OVn nfs://<IP NFS>:/share -g -s 1000m -E /share

Sorry I cannot have a mondo-restore.log logs, the console in the ILO does not allow me to type a character... I returned to a shell (like expert mode) and I cannot do anything (and the machine is very far from me physically)

I browsed the forums and other users have encountered similar problems with the ILO.
One of an issue is to connect a virtual cdrom and start mondoarchive to be sure to have the right modules at time of backup (but not ok in my case)
Other issue : we must join in FORCE_MODS mindi the list of usb modules (this does not work, have you an list of modules?)

I also tried with my physical drive on my station (burned cd and link to ILO) and it did not work

When I get myself mondorescue.iso (/var/cache/mindi/mondorescue.iso) and mindi-bootroot.65600.img (in mondorescue.iso) with mount on my system it works (without boot on CD)

Would you pre-requisite for the ILO is able to mount the cd and untarring all.tar.gz?

Restore - wait long time for raid 1 md device sync

Hello,

Is there an option to disable waiting for raid software sync in case of using software raid?

I was trying today to replace my HDDs (from 100 GB to 2 TB) and looking at /proc/mdstat I have seen that I have to wait 4 hours (probably more as it is a simple estimation).

My system is a quite old one (Centos 5.10) and most probably my SATA controller is the bottle-neck here. However, during OS installation the MD devices are just created and re-sync is done in the background, without interfering with the installation.

I have understand that it is best to wait for resync before do anything else - but could there be an option to disable it in 'expert' mode.

Waiting for your feedback,

In file 
(1) # vi /etc/lvm/lvm.conf

 # By default we accept every block device:
    #filter = [ "a/.*/" ]------>commented  the line
 
 (2) To mount the entries in fstab with the disk name changed the fallowing

#Yast disk

setting -->device name

(3)Made some changes in mindi script
#vi /usr/sbin/mindi

#DENY_MODS="MPS_Driver_Mapper mps octtldrv tscttl streams kqemu fdomain"
DENY_MODS="kqemu vxfen scsi_debug"- - - - >added these entries

unable to restore my system disk

Hi all,

I had a system disk crash when I got back from summer holidays.
Just to remind me how the life is :D

Fortunately, my data disk was ok and I had a mondo save on safe place.
Anyway, as it was time for me to replace my ubuntu system to a Debian
one (I prepared that move for some time) I just installed Wheezy and
reconnect my data disk on it. All was fine.

It was also time for me to test in real conditions my mondo savings with
a new system disk but I never been able to restore anything.

I always get "archive file not found" as my iso files are never mounted.
If I do it by hand it works.

In the logs I can read:
1609 [Main] mondo-rstr-tools.c-≥iso_fiddly_bits#299: Setting isodir to

The full isodir path as defined at line 1611 is not used and so mondo
cannot find the iso file.

If I do it by and, that's ok:

Many thanks in advance help.

  Data disk /dev/sdb and is a LVM PV (1To)

The backup disk is mounted as /dev/sdg under /media/sauvegardes every
friday then a mondorescue is launched at night. A full iso backup is
done the 1st week of the month and differential others. A mondorescue
iso file is also built.
This disk uses /dev/sdg as there are some card readers seen as virtual
disks (/dev/sdc to /dev/sdf)

What I try to do is only restore /dev/sd5 and /dev/sda7

So I do :
The new disk and crashed disk are exactly the same. (1To IBM)
Burn a CD from the mondorescue iso file then partition and format the
new disk as the crashed original disk.

Boot on the mondorescue CD. (expert)
The new system disk is seen as /dev/sde (I don't know why, the 4 card
readers are detected before the new disk)
Plug the backup disk. It is then seen as /dev/sdf
