In UNIX-based operating systems, fsck is used for checking and resolving file system problems. If one or more of your file systems are corrupted, you can easily repair it using fsck command line utility. But, fsck can not be used to check the hard drive functions of under Solaris.
Most of the users’ first experience with the fsck tool comes after their computers crash and situations become quite challenging as they demand recovery. This is essential because the users are under substantial pressure to get their system working again and do not understand what to do.
If you are new to Solaris UNIX and are facing any file system corruption related issue, you should use fsck after un-mounting the file system.
How does fsck work?
UNIX does not mount the file system that wasn’t un-mounted cleanly when the system was shut down last time. Due to the same, the file system may be damaged and mounting a damaged file system would lead to the UNIX system crash.
When computer boots all the file systems are examined to see whether they are clean. If they are not clean then fsck will be used to check out completely.
Using fsck is very important and allows you to have easy Solaris Data Recovery, but sometimes it can cause serious problems. If you run fsck on a mounted file system, it may get corrupted severely and put you in need of Data Recovery Solaris using third party tools.
The data loss may also occur if you mount a corrupt file system after running fsck on it. It will crash the system and make the situation even worse.
Solaris Recovery using third party tools is fully automated and user friendly. Solaris Data Recovery software are used for this purpose. These are third party tools which are capable of carrying out quick and absolute Data Recovery Solaris.
Stellar Information Systems Limited offers two different software for Solaris Data Recovery. These software are available for Sparc and Intel versions of Solaris. Both these software support Solaris Recovery from UFS file system based Solaris volumes.
