bdf

Hi All,

I have started rman filesystem backup of Oracle 8i in HP-UX 11.11. The backup file (????.rman) created was about 150GB and the backup was continuing. It was observed through "bdf" that the filesystem was growing. So when filesystem utilization(total size 140GB) reached about 92% I killed the rman process. But even after this I found that the filesystem utilization was growing and so I removed the ????.rman file as I could see that the timestamp of the ????.rman file was also changing to the current time.

Now when I run bdf I still see the filesystem utilization to be 93% which is 132 GB.
sfds:[root] > bdf /sfds/oracle/backups
Filesystem kbytes used avail %used Mounted on
/dev/vg08/lvol2 140288000 132335120 7891000 94% /sgp-sfds/oracle/backups

sfds:[root] /sgp-sfds/oracle/backups> du -sk
29859064

But actually there is about 30 GB of data in it.

How can I make the bdf understand that the filesystem utilization is about 10%. Also will it allow to write data to this filesystem even though the bdf shows 100% full as actually it is not.

Thanks,
Raje.

Hi Raje,

It sounds like there is still a process running and writing to that file. Even though you deleted the file, the space is still taken up on disk because some process had that file open, and the space won't be released until the process dies. You'll need to see if there are any other rman processes running and try to kill them. Once you get it killed, it should release your disk space.

Hi Raje,
Could it be that rmanprocess is still "writing" (even though you removed the file) ? You can check this with "lsof". Alternatively "fuser" might give an indication.

Hope it helps,
Tom

You can find out what's writing to this filesystem by using

fuser /dev/vg08/lvol2
