Checking for missing files.
Hello all. Is there a way of checking what is on the tape against what is on the disk, to show missing or renamed files on a large scale? Thanks, Trevor. = Stussy said:Knowledge is King! =

mt rewind strangness
Has anyone else noted this behavior? mt rewind returns (completes) before tape is rewound Specifically, When I issue an mt rewind from a shell command line, the tape begins to rewind (lights on drive blinking) and after about 10 seconds the mt command completes and I get my shell prompt for the next command. However, the tape has not yet rewound completely, the drive lights are still blinking. If I issue a second mt command (another rewind or status) that command blocks until the tape is completely rewound before executing and returning. I'm wondering if this is why my amcheck command sometimes fails to find the correct tape in my changer though amdump always does. Perhaps amcheck does an mt rewind and it returns before the tape drive is done rewinding. Then amcheck might issue a command that times-out rather than blocking and thus amcheck thinks that slot has no or the wrong tape. Just musing. -- Jon H.

Its a good muse, and I don't know an answer unless its to do with something local to your system. mt -f /dev/nst0 rewind does an absolute block until the rewind is complete here on a linux 2.4.19 athlon system, and always has. There was a point about 6 or 8 months back up the log when the command in amanda was broken, wrong ioctl or something, but when that occured, the drive had never seen that command at all. And that gave us a lot of false can't find label such and such reports at the time. Have you built and installed the 20020826 snapshot yet? I need to do that yet today, I'm still on 20020823 here. -- Cheers, Gene AMD K6-III@500mhz 320M Athlon1600XP@1400mhz 512M 99.13% setiathome rank, not too shabby for a WV hillbilly
Re: Checking for missing files.
Hi Jon. Thanks for the reply. My objective is when someone accidentally deletes files and doesn't know what file they were, to compare what Amanda has on tape and what is on the file system to see what is different, so I don't have to manually search the tape and the file system to see what is missing and what to restore.

Thanks, Trevor. Ahh, then probably the regular indexes will be sufficient. I presume you are recording, then you have an indexdir defined. In that indexdir will be subdirs for each host. Under the host dir will be subdirs with names based on the disklist entries. In these names the / are replaced with _. My approach would be to make a list of everything the user currently has and compare it to what the index shows is on tape. Assume the user is shmo As root: cd ~shmo/.. # one level above shmo find shmo /tmp/shmo-current # or two levels and do a find home/shmo sort -o /tmp/shmo-current /tmp/shmo-current cd amanda-index-dir-for-shmo's-filesystem # note all the backups since the last level 0. # in my case that would be 20020823_0.gz # 20020824_1.gz 20020826_1.gz 20020827_2.gz for f in 20020823_0.gz 20020824_1.gz 20020826_1.gz 20020827_2.gz do gzip -dc $f | grep /shmo/ | sed 's,/$,,' done | sort | uniq /tmp/shmo-tape # or the command might look for /home/shmo if appropriate # the sed is to remove any trailing /s on dir names that my indexes # have, but the find does not. # now you may have to edit one or the other file to make the leading # part of each line the same For example, the find may not have a / # at the start or might need /home/ added to one file or deleted # from the other. Now you have two sorted lists, what is in shmo's directory tree currently and what is on tape in at least one of the most recent backup set. Of course the for f in ... loop could have been done on all index files to go further back. To compare them use the comm command: # files on tape but not in current dir tree comm -13 /tmp/shmo-current /tmp/shmo-tape # files in current dir tree, not on tape comm -23 /tmp/shmo-current /tmp/shmo-tape # files in both comm -12 /tmp/shmo-current /tmp/shmo-tape Another approach is to amrecover the entire /home/shmo tree in some tmp dir. Then do a dircmp of shmos' current tree with the tmp tree. Then you already have the files on disk and can simply copy them. Hope these make sense and help.

Ongoing issues
I know I've seen this issue here thousand times but I've tried everything I have been able to find, to no avail. When running amcheck as the backup user I'm getting the classic access to [problemhost] not allowed from [backupuser@problemhost] This Amanda installation also backs up remote machines with no problem; it just won't access the local machine to back itself up. Things I've Checked: 1) .amandahosts permissions are set to -rw--- 2) .amandahosts is owned by the backup user 3) .amandahosts has entries [problemhost] [root] [problemhost] [backupuser] 4) the machine is listed in the disklist file (obviously, or it wouldn't generate the error) 5) xinetd.d has an 'amanda' file with the correct backup user shown 6) all of the executables in /usr/local/sbin are owned by the backup user (except amcheck which is owned by root) 7) all of the executables in /usr/local/sbin have permissions rwxr-xr-x (except amcheck which is rwsr-xr-x) By the way we also have another Amanda server backing up itself and some remote machines, and it works fine, and all the above things (except host names, of course) are identical to the machine that works ok.

AMRECOVER Not Working
I've installed Amanda version 2.4.2p2 and have not been able to get amrecover to work. For example, the backup server name is backup.rnd.caribbeanblue.com, the only filesystem to back up is /etc on backup.rnd.caribbeanblue.com, and amrecover is run from the backup server. Running amrecover produces the following: backup:/ # /usr/sbin/amrecover -C daily -s backup.rnd.caribbeanblue.com AMRECOVER Version 2.4.2p2.

host name lookup failed
Pardon my ignorance here, I'm fairly new to the Linux OS, so I'm sure this is old hat to many of you, but... We recently replaced a machine that an Amanda server was backing up remotely--it was working beautifully before. We put it at the same IP address, but gave it a different machine name. The first time we ssh'd to it, got the standard message that the RSA key was missing, so we regenerated the keys for the new machine. Then I deleted the machine from my Known_Hosts file and connected from my Amanda server and accepted the new key. Now I can ssh with no problem, although I have to ssh to the old name, and the prompt shows the new name. If I try to ssh to the new name directly, I get a Name or service not known error. I can live with that. My problem is getting the new machine backed up using the Amanda server. At first, I was getting a FAILED report from Amanda regarding that machine (data timeout). Then I remembered that I had not set up the Amanda client in xinetd, so I added the Amanda service and restarted xinetd. I wasn't sure how to list the machine name in my Amanda disklist file, so as an experiment, I listed both names and also the IP address of the client in disklist and ran Amcheck. I get the message ERROR: (newclientname): [addr (IP address of local Amanda server): hostname lookup failed] ERROR: (oldclientname): [addr (IP address of local Amanda server): hostname lookup failed] ERROR: (clientIPaddress): [addr (IP address of local Amanda server): hostname lookup failed] This Amanda server continues to back up other clients without failure. Since amcheck can't find the remote client using its IP address, I'm assuming it's not a DNS issue. Any ideas? Larry Dunham attachment: winmail.dat
Backing the backup server
I am trying to backup the backup server in amanda and I am a little confused on how to go about it from the documentation you setup a .amandahosts file on the server and the client. Is an entry for the backup server need to be there. If so what should the connect as user be 1) amanda 2) root If this is not the case then how does one configure the backup server?

changer.conf
I am just curious all the people that use amanda on this list what changer do you prefer. I am currently using chg-zd-mtx, but highly thinking about changing my problem is this I am trying to create 2 configs one setup for directories that don't change very much and another config for directories or host that modifiy data alot. So since I ahve a 40 tape library unit with 2 tapes inside it. I split the library in half( for now) and use one tape drive for each config. When I specify the first slot in my changer.conf file on the second config it seems to always load the tape in slot one and not in slot 19 and I don't understand why.

RE: could not get changer info specify a number as tape_device [0-9]
Hi, My question kinda goes along with what Chris Bourne asked earlier yesterday: I have an STK 9730 jukebox. Running amanda on Solaris 2.6. In my amanda.conf file, I specify chg-scsi as my Built In Tape Changer as specified by share/TAPE.CHANGERS. As far as I can see, the configs for chg-scsi is similar to chg-scsi-chio. So, in order for chg-scsi to understand ''changerfile'' as more than just a ''slot counting'' file, I specify my ''tapedev'' as a ''0''. When I try to ''amdump'', I see this error in my amdump.1 log file: amdump.3:driver: result time 12.873 from taper: TAPE-ERROR [tape_rdlabel: tape open: 0: No such file or directory] So I change the ''tapedev'' entry in amanda.conf back to /dev/rmt/2bn Then amdump works just fine. Okay great, now I wish to run ''amlabel'' in order to relabel the tape to test out ''amdump'' a bit more. $ amlabel -f DailySet1 DailySet10826 slot 1amlabel: could not load slot "1": check your config and use an config file for chg-scsi Slot 1 does indeed correspond with /dev/rmt/2bn So in order to run ''amlabel'' I gotta specify my ''tapedev'' as '0'...and in order to run ''amdump'' I gotta specify my ''tapedev'' as /dev/rmt/2bn I am assuming that the ''changerdev'' is the /dev pathname for the robotic arm. I know if the changer script I am using were ''chg-mtx'' as opposed to chg-scsi, then I would likely specify ''chagerdev'' the same as ''tapedev''. What am I doing wrong here? Should I switch changer scripts, maybe to chg-scsi-chio?? I have included, the errors I get in the log, and portions of my amanda.conf file and scsi-chg.conf files thanks, Rich Quinn =amdump.1LOG FILEOUTPUT= changer_find: looking for DailySet10820 changer is searchable = 0 changer: opening pipe to: /usr/local/amanda/libexec/chg-scsi -slot currentchanger: got exit: 0 str: 1 /dev/rmt/2bntaper: slot 1: date X label DailySet10826 (first labelstr match)changer: opening pipe to: /usr/local/amanda/libexec/chg-scsi -slot nextchanger: got exit: 2 str: 2 slot 2 move failedtaper: fatal slot 2: slot 2 move failedchanger: opening pipe to: /usr/local/amanda/libexec/chg-scsi -slot 1changer: got exit: 2 str: 1 slot 1 move faileddriver: result time 234.461 from taper: TAPE-ERROR [slot 1 move failed]dump of driver schedule before start degraded mode: ==PART OF THEamanda.conf= tpchanger "chg-scsi" # use HP changerchangerfile "/opt/encap/amanda/etc/amanda/DailySet1/chg-scsi.conf"changerdev "/dev/rsst0"tapedev "0" # the no-rewind tape device to be used ===PART OF THE chg-scsi.conf number_configs 1eject 0sleep 60cleanmax 10 changerdev /dev/rsst0## Drive 0#config 0drivenum 0dev /dev/rmt/2bn -Original Message-From: Chris Bourne [mailto:[EMAIL PROTECTED]]Sent: Monday, August 26, 2002 5:53 PMTo: [EMAIL PROTECTED]Subject: could not get changer info specify a number as tape_device [0-9] Hello, I need help with figuring out why amanda is giving me these errors.

Re: AMRECOVER Not Working
I'm running it on a server with SuSE 8.0. It came with the 8.0 distro, so I didn't need to compile anything. Regarding security, there are also no Amanda kerberos port entries in my /etc/services by default. The strange thing is that I have tested Amanda in doing back ups of two other SuSE servers from backup.rnd.caribbeanblue.com. The backups complete without any errors, and I'm not able to do amrecovers from them as well. What I am seeing is that backup.rnd.caribbeanblue.com is able to back itself and other servers up, but for some reason, will not allow amrecover to work despite indexing. The backup server is accessing the clients, but the client (even if on the server) can not access the server. .amandahosts has: localhost amanda localhost root backup amanda backup root backup.rnd.caribbeanblue.com amanda backup.rnd.caribbeanblue.com root What does work is amrestore, as in: /usr/sbin/amrestore /dev/nst0 backup This pulls the .o image file containing /etc off of tape. However, it would be nice to just use amrecover for extracting needed files or directories. Eric On 8/27/02 2:16 PM, Eric Swindell [EMAIL PROTECTED] wrote: Tony, I have index yes in amanda.conf.

Question in regards to Label Printing.
Good Day
I am a newbie with Amanda so please forgive my ignorance if the answer to this
question is more obvious than it appears to me.
I have set Amanda 2.4.3b3 up on a FreeBSD 4.4 box. I have it successfully backing up
a test network and I am very pleased with
the results. Now comes the next step cataloging and labeling my tapes.
I have tried to setup Amanda to print DLT labels (using the built-in DLT.ps template)
the catch here is that I do not want to
print directly to a printer. I would like to print it to a file (We like to keep
everything digitally)
Below is an excerpt from my amanda.conf file. If anyone has any suggestions on how to
make this work I would be very happy to
hear them. I have spent the past 4 hours searching the list with no luck.
Thanks!
tapetype DLT# what kind of tape it is (see tapetypes below)
define tapetype DLT {
comment DLT tape drives
lbl-templ /usr/local/etc/amanda/Backup/DLT.ps
length 4 mbytes # 20 Gig tapes
filemark 2000 kbytes# I don't know what this means
speed 1536 kbytes # 1.5 Mb/s

Re: AMRECOVER Not Working
I finally figured it out. It was either a space or an empty line in /etc/inetd.conf. I don't know why this matters to inetd, but it brings me back to my days doing vax assembly. This is what I had in /etc/inetd.conf: # [blank line...] # amanda backup client amanda dgram udp wait amanda /usr/lib/amanda/amandad amandad # When I uncommented the client entry (amanda dgram...), I must have accidentally left a space in the place of the # marker. Before the top comment, there was a blank line. I deleted the line as well. After restarting inetd.conf, it now works! I can now do an amrecover from the backup server as well as the client servers. You were right about the tapeserver (-t) parameter. You need to add that when running amrecover from a client.

Devices
Hello, I am running amanda 2.4.2p2 on FreeBSD 4.6.2. Well I hope to be anyways. The thing I cannot seem to figure out is this. I am using a quantum ATL L500 tape changer with a DLT8000-40 tape drive. The devices for the /dev/sa device are numbered /dev/sa0 /dev/sa0.0 /dev/sa0.1 /dev/sa0.2 /dev/sa0.3 I am trying with the changer.conf to name the slots at the end but when I do amlabel -f normal Z01 slot 0 I get slot 0 empty. What I do not understand is, does each /dev/sa0.* device pertain to a slot in loader or do i need to make sa1 sa2 sa3 and so on? Or am I totally lost? Thanks for any and all replies greg
