TRU64 5.1 File size limits

Cara Rollins — Mon, 16 Jan 2006 16:42:47 GMT

There appears to be something odd with file limits When copying files (cp) I'm getting an odd 'Exceeded file size limit' message.

cp -R /dir1/dir1.2 /dir2

Any ideas? I'm copying 52 GB of data and it quits after about 20GB.

Does anyone know of any file size limits? I'm assuming it's hitting a large file and stopping.

Check your session limits with ulimit -a. I think that you have file limit set:

ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) 4194304
stack(kbytes) 32768
memory(kbytes) 16322280
coredump(blocks) unlimited
nofiles(descriptors) 4096
vmemory(kbytes) 8388608

Use ulimit -f to modify the value.

Hello Mr Cara Rollins

This Error is due to the number of files in the source directory and has nothing to do with the size of individual files.
You can try copying limited files (may be a set of 200 files)
This will resolve your issue.

Thanx

Hi,

aren't you mistaking that with the resolution of * by the shell? Since he is copying recursively, this should be no problem.

greetings,

Michael

This is advfs, yes.

It isn't the ulimit settings. The settings are the same as another server where the copy works fine.

time(seconds) unlimited
file(blocks) unlimited
data(kbytes) 131072
stack(kbytes) 8192
memory(kbytes) 2040360
coredump(blocks) unlimited
nofiles(descriptors) 4096
vmemory(kbytes) 4194304

It is definitely the file size. I get the same error copying one 1 GB file.

Also, the files over 1GB are getting truncated to 1GB.

Are you using quotas on that file system? use quota/repquota to verify that.

Cara Rollins — Tue, 17 Jan 2006 13:24:17 GMT

is that a command?

Can you also post the results of:

df -ik /dir2
showfdmn domain_name
showfsets domain_name fset_name

Where domain and fset name corresponds to the one that holds /dir2

I think Ferreira is right. It is defiantly just because of your quota limitation on your destination Fileset (/dir2) where you try to copying your 52 GB data. Nothing related to ulimit.

Can you also post the results of:

#/sbin/advfs/vdf -k -l domain#fileset
