During all my ODA projects where I need to perform patching operation, I’m using odabr tool. This tool is really easy to use and well designed. It offers the possibility to create snapshot on the \/, \/u01 and \/opt LVM file systems as well as a physical copy (rsync) of the files to an external destination storage as NFS. This is powerful in case you would like to get just one file back. The tool, as well as the user guide, can be found on Oracle Doc ID 2466177.1. I recently faced some errors when the tool is performing EFI device backup, and thus resulting in failing without been able to create any snapshot. I wanted to share my finding here, and maybe for you to win some troubleshooting time.<\/p>\n

<\/p>\n

How to install the tool?<\/h2>\n

Easy to install. You just need to download from the Doc ID the odabr-2.0.1-66.noarch.rpm package.<\/p>\n

Check that the package is not already installed:<\/p>\n

[root@ODA01 patch]# rpm -qa | grep -i odabr
\n[root@ODA01 patch]# <\/code><\/p>\n

Install the tool:
\n[root@ODA01 patch]# ls -ltrh
\ntotal 5.2G
\n-rwxrwxrwx 1 root root 5.2G Jul 19 15:00 p30403673_1911000_Linux-x86-64.zip
\n-rw-r--r-- 1 root root 27K Jul 21 09:00 odabr-2.0.1-66.noarch.rpm
\n

\n 
\n[root@ODA01 patch]# rpm -qa | grep -i odabr
\nodabr-2.0.1-66.noarch<\/code><\/p>\n

Making a snapshot backup<\/h2>\n

First we will need to check if we have enough place in the physical volume.<\/p>\n

[root@ODA01 patch]# pvdisplay
\n --- Physical volume ---
\n PV Name \/dev\/md126p3
\n VG Name VolGroupSys
\n PV Size <446.15 GiB \/ not usable 23.00 MiB
\n Allocatable yes
\n PE Size 32.00 MiB
\n Total PE 14276
\n Free PE 5444
\n Allocated PE 8832
\n PV UUID VyihMy-xEoI-SgKi-Apku-PBIS-BTnf-v2tsfU<\/code><\/p>\n

In our case we have 5444 Free PE, one PE has a size of 32 MiB, thus making here about 170 GB available for snapshots.<\/p>\n

By default the tool is assigning 190 GB snapshot to the 3 file systems (\/, \/u01 and \/opt). If we have enough free space, we could simply run the following command to create snapshots backup:
\n[root@ODA01 patch]# \/opt\/odabr\/odabr backup -snap<\/code><\/p>\n

In our case knowing we only have 170 GB free, we might need to adjust the snapshots size.<\/p>\n

With a df command we will first check how many place is needed :
\n[root@ODA01 patch]# df -h \/ \/u01 \/opt
\nFilesystem Size Used Avail Use% Mounted on
\n\/dev\/mapper\/VolGroupSys-LogVolRoot 30G 7.1G 21G 26% \/
\n\/dev\/mapper\/VolGroupSys-LogVolU01 118G 77G 36G 69% \/u01
\n\/dev\/mapper\/VolGroupSys-LogVolOpt 99G 53G 41G 57% \/opt<\/code><\/p>\n

From there we will size each snapshot size (rsize for \/, usize for \/u01 and osize for \/opt) :
\n[root@ODA01 patch]# \/opt\/odabr\/odabr backup -snap -rsize 15 -usize 90 -osize 60<\/code><\/p>\n

EFI device backup issue<\/h2>\n

Running it could fail with EFI device backup issue:
\n[root@ODA01 patch]# \/opt\/odabr\/odabr backup -snap -rsize 15 -usize 90 -osize 60
\nINFO: 2021-07-21 09:08:08: Please check the logfile '\/opt\/odabr\/out\/log\/odabr_84675.log' for more details

See the error :
\nERROR: 2021-07-21 09:08:10: Error running fsck over \/opt\/odabr\/out\/hbi\/efi.img
\nERROR: 2021-07-21 09:08:10: Command: 'fsck -a \/opt\/odabr\/out\/hbi\/efi.img' failed as fsck from util-linux 2.23.2 fsck.fat 3.0.20 (12 Jun 2013) 0x25: Dirty bit is set. Fs was not properly unmounted and some data may be corrupt. Automatically removing dirty bit. Performing changes. \/opt\/odabr\/out\/hbi\/efi.img: 20 files, 1100\/63965 clusters<\/code><\/p>\n

This mainly means that the the image being checked was not properly unmounted and contains dirty bits. This is explained as well in Doc ID 2679511.1.<\/p>\n

Solution<\/h2>\n

In order to resolve this issue, simply run fsck on the \/boot\/efi partition before running the tool.<\/p>\n

First check which partition the \/boot\/efi is mounted on :
\n
\n[root@ODA01 ~]# lsblk | grep efi
\n\u2514\u2500sda1 8:1 0 500M 0 part \/boot\/efi
\n<\/code><\/p>\n

Then umount the \/boot\/efi partition :
\n
\n[root@ODA01 ~]# umount \/boot\/efi
\n<\/code><\/p>\n

Run fsck on the \/boot\/efi partition :
\n
\n[root@ODA01 ~]# fsck.vfat -a \/dev\/sda1
\nfsck.fat 3.0.20 (12 Jun 2013)
\n0x25: Dirty bit is set. Fs was not properly unmounted and some data may be corrupt.
\n Automatically removing dirty bit.
\nPerforming changes.
\n\/dev\/sda1: 20 files, 1100\/63965 clusters
\n<\/code><\/p>\n

Mount the \/boot\/efi partition again :
\n
\n[root@ODA01 ~]# mount \/boot\/efi
\n<\/code><\/p>\n

Check that the \/boot\/efi file system is well mounted again :
\n
\n[root@ODA01 ~]# df -h \/boot\/efi
\nFilesystem Size Used Avail Use% Mounted on
\n\/dev\/sda1 500M 8.6M 492M 2% \/boot\/efi
\n<\/code><\/p>\n

And then running odabr tool again will make the snapshots creation now successful:<\/p>\n

[root@ODA01 hbi]# \/opt\/odabr\/odabr backup -snap -rsize 15 -usize 90 -osize 60
