iSCSI – be careful
I never mind iSCSI can’t be mounted more than 1 server simultaneously.
Really it can but will damage a file system.
I tried it :).
2 FS servers were mounted 1 iSCSI disk simultaneously.
In the beginning it seemed OK.
I did some transfer operations on a 1 server then on a 2 server.
Everything was ok.
Suddenly I got an error that I couldn’t copy a file with a strange description.
I remounted disks and got them inaccessible.
Firstly I started to recover files with some utils – it was possible.
Later I just run chkdsk /F against these disks and the errors were fixed.
Some files were lost I think.
So, don’t do experiments with it :).
