Corrupted Dabatabase

The issue sounds more like your server than just Postgres - search the
net for "read only file system" for your OS.

Hello Everydody,

My database is corrupted, each time i try to list all the tables in
the database i have got the following message

hla2db=> \d
ERROR: could not open relation 1663/16385/1255: Read-only file system

I read that my best option is to use my backup. Before using my backup
i would like to remove all databases in postgresql and create
everything again from scratch. Unfortunatlly i can't see the list of
databases, althought i am able to create databse

can you suggest what to do? is it a good idea to reinstall postgresql?

May be you filesystem is mounted read-only after power loss or some OS
crash?

What OS do you have - WIndows or some kind of Unix (Linux, etc). Also
what file system Postgresql data dir is using?

hi

thank you for your quick answer,

I am working with linux. here you have the output of uname --all

Linux XXX at 2.6.18-274.3.1.el5 #1 SMP Tue Sep 6 20:13:52 EDT 2011 x86_64
x86_64 x86_64 GNU/Linux

And the filesystem is ext3

i was able to work with the database until last week when i was indexing
the database. the problem came when i tried to cancel a \di command

as far as i know nothing changed since the last time i was working last
week.

Have you run fsck on the filesystem? Is there any messages in
/var/log/messages?

How did you cancel the command?

Also elaborate on what you mean by 'indexing the database'?

You probably have a HDD problem.
Try a "cat /proc/mounts" and see if partition is mounted read only.

hello again

to cancel the execution of the \di i used cntl+c, the output for the cat
/proc/mounts returns

/dev/mapper/ddf1_4c5349202020202010000055000000004711471100001e78p1 /home
ext3 rw,data=ordered 0 0

i when i say i was indexing a table, i mean that i was executing a "create
index" command
