Hello.
I've recently upgraded to amanda 2.5.0p2 and switched the changer from the
obscure chg-scsi to the much better chg-zd-mtx. All things have been running
great for the past weeks, until yesterday.
I got this error:
*** A TAPE ERROR OCCURRED: [No writable valid tape found].
Some dumps may have been left in the holding disk.
Run amflush to flush them to tape.
The next tape Amanda expects to use is: ISR003.
This morning I did a "amtape ISR show" which resulted fine:
changer: got exit: 0 str: 4 6 1
changer_query: changer return was 6 1
changer_query: searchable = 0
amtape: scanning all 6 slots in tape-changer rack:
changer_find: looking for NULL changer is searchable = 0
changer: got exit: 0 str: 4 /dev/nst0
slot 4: date 20060808 label ISR004
changer: got exit: 0 str: 5 /dev/nst0
slot 5: date 20060809 label ISR005
changer: got exit: 0 str: 6 /dev/nst0
slot 6: date 20060807 label ISR006
changer: got exit: 0 str: 1 /dev/nst0
slot 1: date 20060810 label ISR001
changer: got exit: 0 str: 2 /dev/nst0
slot 2: date 20060811 label ISR002
changer: got exit: 0 str: 3 /dev/nst0
slot 3: date 20060806 label ISR003
Greping the amdump log one can find the error:
changer: opening pipe to: /usr/local/amanda/libexec/chg-zd-mtx -info
changer: got exit: 0 str: 5 6 1
changer_query: changer return was 6 1

slot 2: read label `ISR002', date `20060811'
slot 3: not an amanda tape (Input/output error)
slot 4: read label `ISR004', date `20060808'
driver: result time 491.656 from taper: TAPE-ERROR [slot 5: read label

slot 6: read label `ISR006', date `20060807'
slot 1: read label `ISR001', date `20060810'

slot 3: not an amanda tape (Input/output error)
slot 4: read label `ISR004', date `20060808'
So it seems the tape on slot 3 has an error. However, I ran amverify on tape
ISR003 and no errors were found!
$ amtape ISR slot 3
changer: got exit: 0 str: 3 /dev/nst0
amtape: changed to slot 3 on /dev/nst0
$ amtape ISR current
changer: got exit: 0 str: 3 6 1
changer_query: changer return was 6 1
changer_query: searchable = 0
amtape: scanning current slot in tape-changer rack:
changer: got exit: 0 str: 3 /dev/nst0
slot 3: date 20060806 label ISR003
Any clues?
Cheers,
Rodrigo
