Description of problem:
Installation fails with the message in subject just after (or while) checking
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install RHEL4-U7 tree from 20080418
+--------+ Dependency Check +---------+
| Checking dependencies in packages |
| selected for installation...rpmdb: write: 0x3896790, 16384: No space left on
installation proceeds without errors
The error messages from other executions:
rpmdb: write: 0x319d740, 16384: No space left on device
rpmdb: write: 0x32163d0, 16384: No space left on device
the first hex number is different but the second one is the same as in comment #0.
We have ramdisk_size=12288 argument for all machines that failed. Is this
something that may be causing the problem?
IIRC in RHEL 4, anaconda uses rpm's dependency resolution mechanism and rpm
caches the dependency lookups in BDB, if that goes to a ramdisk... It's by no
means new behavior, but maybe the ramdisk contents are now just that little bit
closer to max than it was before. So yeah, I suppose increasing ramdisk_size
see comment #6 for the actual ramdisk_size value but I was told by anaconda
folks that this parameter is not taken into account anymore.

even with ramdisk_size=50000 I can still see the error.
*** Bug 443673 has been marked as a duplicate of this bug. ***
I got nowhere on this today. Can someone see what the output of 'df' looks like
on these systems both before and, if possible, after the error? anaconda.log and
syslog might also be of some use.
Also, can someone give a little more information about ramdisk_size getting
ignored? Specifically, what does decide the size of the ramdisk? A quick look at
an i386 system seems to support the notion that the ramdisk_size parameter does
nothing (6M rootfs with ramdisk_size=8192 on cmdline).
Just a few datapoints from rpm POV:
- like said, rpm caches dependency lookup results on disk (Berkeley DB) if
possible, that's why it would be writing to disk at that point
- the caching has been there for a long time, certainly in all RHEL 4 versions
- I looked through recent anaconda changelogs and didn't see anything obvious
that would affect this, and the fact it only happens on ia64 tells it's not a
very fundamental change in anaconda, otherwise we'd see this on all platforms
- if it comes to that, it is possible to disable the caching in rpm (a one-liner
patch) at a slight performace cost, but that'd be treating the symptoms instead
of the disease

anaconda.log and syslog are available in any of the links in comment #4 (look
for "anamon" link)
I can provide `df' just after stage2 has started. Is this what you refer to
"before"? Unfortunately after the error it's not possible to switch to other tty
and getting `df' will be hard I think. jgranado is trying to get more info on
that using pdb.

Created attachment 303459 [details]
output of df after stage2 is loaded
Created attachment 303460 [details]
output of df after the error occured
Both outputs show that space is used at 100%. The only difference is the
everything else is the same

Increase the fs size.
Ok, I think I found the reason for this issue.
We just don't have enough ramdisk. the ramdisk_size option works fine, we just
dont make a good use of it. The ramdisk grows, what does not grow is the
filesystem that we use. It needs to be bigger.
The reason for this issue is most likely something new that uses the ram disk
and we didn't know about it. What needs to be done is to increase the
Question is. Will this increase be enough?

Testing with initrd.img provided by Joel:
* default package set install completed
* everything package set completed
I didn't observe the rpmdb error and was able to reboot into the newly installed
Please commit the fix and build a new package ASAP.
Fixed in anaconda-10.1.1.88-1.
