| Xfsdump/Xfsrestore Troubleshooting Questions |
| ============================================ |
| |
| SGI Support (relevant for IRIX customers only) |
| ---------------------------------------------- |
| * What is the customer support case number? |
| * Is there an associated engineering bug number? |
| * Do you have any existing contacts within SGI? |
| |
| General |
| ------- |
| * Have you run xfsdump or xfsrestore before? |
| * Is this a new problem? |
| And if so, what has changed since xfsdump or |
| xfsrestore last worked correctly? |
| |
| Operating System (OS) |
| --------------------- |
| * What versions of the OS are you using now and |
| when the dump was made ? |
| (IRIX: uname -Ra or Linux: uname -a, cat /etc/issue) |
| * What patches were installed for the OS ? |
| * If Linux, what version of the xfsdump package |
| are you using? |
| (rpm -q xfsdump) |
| * Is there anything in the /var/adm/SYSLOG file for the period that |
| xfsdump or xfsrestore was run? |
| |
| |
| File System (FS) |
| ---------------- |
| * How big is the filesystem being dumped ? |
| (df -kl) |
| * Does the filesystem have quotas enabled ? |
| (mount) |
| * Is the filesystem managed with DMF ? |
| * Does the file system use Security attributes such as ACLs ? |
| * Are extended attributes used in the filesystem ? |
| * Is the filesystem controlled by CXFS, or the host part of a cluster? |
| |
| Tape System |
| ----------- |
| * Is TMF or Openvault used to manage the tapes ? If so, which versions? |
| * What kind of tape drive is used ? |
| * On IRIX, what kind of tape driver is used - tpsc or ts ? |
| (eg. attr -g _drivername /dev/rmt/tps4d6) |
| * Is the drive used in variable or fixed block mode ? |
| (IRIX: look at the path for the tape specification) |
| (Linux: mt -f /dev/st0 status; and report the blocksize) |
| * How many tapes were used for the dump ? |
| |
| Dump/restore commands |
| --------------------- |
| * What was the xfsdump/xfsrestore command lines used ? |
| * What was the output from the commands ? |
| * If the FS is not too large, |
| what is the output with the -v5 option ? |
| * How big was the dump ? |
| * What drive strategy was used in the commands? |
| (xfsdump -v3 ... |grep "instantiat") |
| (xfsrestore -v3 ... |grep "instantiat") |
| If you have the -v5 output, then just grep for "instantiat". |
| * If dumping/restoring to/from a remote host, |
| what is the OS version of that host? |
| * If xfsdump/xfsrestore seem to take a really long time, use the -p |
| option to get progress output. |
| * What is the output of 'xfsdump -I' ? |
| |
| |
| Misc |
| ---- |
| * If the problem is related to files not being dumped or restored, and |
| you know the inode numbers from the xfsdump/xfsrestore output, what |
| files are they associated with? |
| (IRIX: xfs_ncheck -i <ino /dev/dsk/<disk_device) |
| (Linux: find /<mntpt -local -inum <ino ) |
