Re: SV: FAILED [spawn /bin/gzip: dup2 out: Bad file descriptor] on 2.6.1p2
Hi, just wanted to send you an update on this issue. Switching to auth=bsdtcp completely solved my problem. The working line from /etc/inetd.conf (for openbsd-inetd, and the amanda-user being "backup") is: amanda stream tcp nowait backup /usr/lib/amanda/amandad amandad -auth=bsdtcp amdump amindexd amidxtaped During the last 7 days there hasn't been a single failed backup on any of my previously affected systems. Thank you for your support! Volker

Re: SV: FAILED [spawn /bin/gzip: dup2 out: Bad file descriptor] on 2.6.1p2
Hello again, unfortunately my dup2-problems reappeared after that one night when it was working, I still have the same error on my machines. so far I have only changed the entry in /etc/inetd.conf (I'm using openbsd-inetd) from: amanda dgram udp wait backup /usr/lib/amanda/amandad amandad -auth=bsd amdump amindexd amidxtaped to: amanda dgram tcp wait backup /usr/lib/amanda/amandad amandad -auth=bsd amdump amindexd amidxtaped and of course restarted the inetd process. Are there any other places I need to adapt when "completely switching amanda to tcp"? Is auth=bsdtcp mandatory?

Thank you Gunnar and Dustin! I switched to tcp on one host yesterday and it worked fine so far. I will observe this for the next couple of days and report back to you.

Switching to tcp instead of using udp cured those problems. -- GG -Ursprungligt meddelande- Från: owner-amanda-us...@amanda.org [mailto:owner-amanda-us...@amanda.org] För Dustin J.

FAILED [spawn /bin/gzip: dup2 out: Bad file descriptor] on 2.6.1p2
Hi, I'm having a bit of a problem on *some* servers concerning failed backups with the error message: lev # FAILED [spawn /bin/gzip: dup2 out: Bad file descriptor] usually these failed backups are "successfully retried", but sometimes I get the same error twice and the backup for the day fails completely. This only happens on servers backing up windows clients via smb-share/"smbclient" which are running amanda version 2.6.1p2. Servers with Linux clients are not affected and other versions of amanda backing up windows clients are also not affected. Additionally, as I said, this does not happen all the time and not always with the same clients. I verified amanda-user-access to /dev/null and I would rule out that the file systems are suddenly corrupt on all these different servers. I would like to know what this error message means and how to fix it or maybe you can point me in the right direction. If you need any more information, please tell me. Thank you in advance, Volker some detailed output from sendbackup.*.debug (this time failed and then retried successfully): 1270767389.972013: sendbackup: start: serverfqdn://ipaddr/backupshare$ lev 1 1270767389.972046: sendbackup: pipespawnv: stdoutfd is 50 1270767389.972078: sendbackup: Spawning "/bin/gzip /bin/gzip --fast" in pipeline 1270767389.972196: sendbackup: gnutar: pid 24511: /bin/gzip1270767389.972213: sendbackup: pid 24511: /bin/gzip --fast 1270767389.972347: sendbackup: critical (fatal): error [spawn /bin/gzip: dup2 out: Bad file descriptor] 1270767389.972928: sendbackup: gnutar: backup of \\ipaddr\backupshare$ 1270767389.973070: sendbackup: pipespawnv: stdoutfd is 6 1270767389.973188: sendbackup: Spawning "/usr/bin/smbclient smbclient "ipaddr\\backupshare$" -U username -E -d0 -Tqcg -" in pipeline 1270767389.976787: sendbackup: Started index creator: "/bin/tar -tf - 2>/dev/null | sed -e 's/^\.//'" 1270767389.979324: sendbackup: gnutar: /usr/bin/smbclient: pid 24513 1270767389.979343: sendbackup: Started backup software versions on affected servers: the OS is Debian Lenny amanda 2.6.1p2 gzip 1.3.12-6+lenny1 tar 1.20-1 smbclient 3.2.5-4lenny9
