Hi all,
Here I got the question. Little tough, about swap usage and /tmp file
system. I request all to reply immediate.
I got Sun - Cluster installed on the system. This is having following
configuration,
####################
# swap -l
swapfile dev swaplo blocks free
/dev/vx/dsk/swapvol1 133,8 16 2049824 1278928
#########################
# grep -i swap /etc/vfstab
/dev/vx/dsk/swapvol1 - - swap - no -
swap - /tmp tmpfs - yes -
#NOTE: volume swapvol (swap) encapsulated partition c0t0d0s1
/dev/vx/dsk/rootdg/swapvol /dev/vx/rdsk/rootdg/swapvol /var/tmp
ufs 3 yes -
##################
# swap -s
total: 928264k bytes allocated + 224880k reserved = 1153144k used, 621440k
available
############################
# df -k /tmp
Filesystem kbytes used avail capacity Mounted on
swap 633888 2064 631824 1% /tmp
# df -k /tmp
Filesystem kbytes used avail capacity Mounted on
swap 633240 2064 631176 1% /tmp
# df -k /tmp
Filesystem kbytes used avail capacity Mounted on
swap 634688 2064 632624 1% /tmp
I can understand, if the values in the swap -s change, like all values may
change, as its virtually allocated, and memory is also involved, which is
freed and used as per the requirement.
My question is I am seeing that, /tmp also varies, which is quite
unanswering for me to the customer, who found this.
And can somebody tell me that, what exaclty I shall do to find out, swap
used by system and thus by users. Please clarify. Please immediate.
I will summerize, Please reply immediate, thanks in advance. I have posted
this message twice, but I received a mail saying awaiting for approval,
please clarify this too.
cheers
regards
Prashant Zanwar
