How to fix the warning "ceph MDS cache is too large (2GB/1GB)" and is it necessary?

Question

Proxmox

There is Proxmox for 3 nodes. From its interface, ceph is raised in a regular way. Periodically, one (arbitrary) from the MDS in the proxymox interface generates a warning from the header. In the console it looks like this:

[email protected]:~# ceph -s
  cluster:
    id:     36229d63-223e-4511-94f4-2069eeb50b6f
    health: HEALTH_WARN
            1 MDSs report oversized cache
 
  services:
    mon: 3 daemons, quorum px0,px1,px2
    mgr: px1(active), standbys: px0, px2
    mds: cephfs-1/1/1 up  {0=px1=up:active}, 2 up:standby
    osd: 6 osds: 6 up, 6 in
 
  data:
    pools:   3 pools, 288 pgs
    objects: 1.59M objects, 1.12TiB
    usage:   3.37TiB used, 1.87TiB / 5.24TiB avail
    pgs:     288 active+clean
 
  io:
    client:   821KiB/s wr, 0op/s rd, 67op/s wr

After a while, the warning disappears on its own:

[email protected]:~# ceph -s
  cluster:
    id:     36229d63-223e-4511-94f4-2069eeb50b6f
    health: HEALTH_OK
 
  services:
    mon: 3 daemons, quorum px0,px1,px2
    mgr: px1(active), standbys: px0, px2
    mds: cephfs-1/1/1 up  {0=px1=up:active}, 2 up:standby
    osd: 6 osds: 6 up, 6 in
 
  data:
    pools:   3 pools, 288 pgs
    objects: 1.59M objects, 1.12TiB
    usage:   3.37TiB used, 1.87TiB / 5.24TiB avail
    pgs:     288 active+clean
 
  io:
    client:   1.98KiB/s rd, 1.37MiB/s wr, 0op/s rd, 130op/s wr

In the ceph config, the cache size is set to 6Gb - I already wrote this, trying to cope with the error, but no effect (of course, I restarted all the nodes).

         mds standby for name = pve

         host = px0
         mds standby for name = pve

[mon.px0]
         host = px0
         mon addr = 10.0.0.50:6789

[mon.px1]
         host = px1
         mon addr = 10.0.0.51:6789

[mon.px2]
         host = px2
         mon addr = 10.0.0.52:6789

Answer 1

As an option!?
Remove everything and leave only:

.catalog .productblocks .product .product_wrapper .get_calculating {
    text-align: center;
    margin-top: 30px;
}

Answer 2

it 's not quite clear
.
top: 50%;
margin-top: -...px; // only if the child has a fixed height, set half of this height with a negative margin (this is vertically, use the same logic horizontally).
Another option is to use flexes, examples of use can be found here
. In your case, it’s not clear why positioning is there.
And what kind of scroll is in question is also not clear.
