find more information on ext2/3/4 filesystem
In my previous post on check filesystem regurlarly, I mentioned tune2fs. That tool give quite a lot of information. But just in case, you did not find what you are looking for in the output, then you can get much more information on these partitions with the dumpe2fs command.
Continue readingfindmnt – find all the mounts and their source
If you are looking for the source of a mount and the various options used in the mount, then the quickest way to get that is ::
findmnt
By default, with no parameters, it lists all the mounts in a tree like view and all the options used to mount the path. It also lists the source of the mount.
By default again, it uses some capabilities of the terminal to show the tree which you can disable with the option “-a”.
Continue readingFind directory/file with inode number
Couple of days back, I was getting the following error:
Directory inode 2362521 has an unallocated block #245823. Allocate?
And this continued for hours together and I was in a hurry. Did not really care about the error and all I wanted was to get rid of the error but for that I needed to get to the file/directory with inode number mentioned in the error and finally “find” command came to rescue:
Continue readingSet some disk params to be safe
It is always “Better safe than sorry” so, here are some things you
should do..
First check fstab, if you have partitions other than root then use UUID instead of device:
UUID=a8f13a0d-3f1f-42e4-b076-f44b4163306c /mnt/Backup ext4 defaults,relatime 1 2
Then entries for all your mounts should be like above.
Points to note here :
Disk is mounted using the UUID and not with /dev/sdXX. This ensures
that even if your disk ids change, you will be able to mount them. To
get the partition UUID, you can execute :
vim maps – simple commands to do stuff.
Some time back, I was working on some script for logging and I wanted to change the class to function like this:
$logger->Debug("Test string");
loggerFunc("Debug", "Test String");
As you can see, this change could be quite frustrating if you have quite a few references. And thus vim comes to rescue.
Simple map like ::
:map ,mm :s/(.*)$logger->(.*)((.*)).*/1loggerFunc("2",3);/
and then I can do “/$logger->” and then “n” to go to next match. Just do “,mm” and the line is re-factored.
