Management of Filesystems / EXT3 ?
I have been surfing around looking for info. on how to manipulate ext3 filesystems, and so far found everything about the advantages, capabilities etc. of ext3 but nothing about the tools and how to manipulate ext3 filesystems.
Anyway, my question is :
Is there a tool like AIX's smitty lvm (extendvg, reducevg) which allows you to expand/extend/reduce an ext3 filesystem ? Why you ask, well, my /var directory which holds my spool/mail directory is full and I need to extend it for more space to hold mails. Any help ?
1. Is there a command which allows to view disk space on the harddisk which has not been allocated ?
2. Is there a command to show the paging space (ie AIX:lsps) in linux ?
3. Is there a tool that allows for the backup and restore of the root filesystem ie AIX's mksysb or something similar in Linux ?
4. Is there any website that I can go to, to get more info on linux filesystem management capabilities and tools ?
Sorry for the long questions, I have been using AIX and Linux for some time and am not familiar with ext3 at the moment.
Thanks in advance.
